Improvements relating to the Production and Manufacture of
Methylated Spirit and the Treatment of the Bye-products Derived
therefrom.
I ALEXANDRE MANBRÉ Senior of 13 Osborne Terrace Clapham Road in the County
of Surrey Brewer and Sugar Manufacturer do hereby declare the nature of this inven-
tion to be as follows:-
My Invention relates to an improved process of producing or manufacturing
methylated spirit direct from amylaceous substances contained in grain, cereals, roots
and other vegetable substances and also from suitable wood and wood tar and the
treatment of the byo products for the production of charcoal and manure.
By the present process, methylated spirit produced by merely mixing ordinary
spirit made from grain cereals and molasses and the bye product derived from the
rectification of spirit together with naphtha spirit which is a product obtained by the
calcination of wood.
The object of using naphtha spirit is to denature the quality of the ordinary spirit
so as to render it undrinkable & only suitable for the production of varnishes, india
rubber and other similar goods and as caloric. Methylated spirit thus produced is
often deficient in quality owing to the difficulty in effecting a proper combination of
both spirits and it is also costly to produce.
Potato spirit is from time to time used as a substitute for grain spirit but owing to
its want of body and easy oxidation and evaporation it produces varnishes and other
goods of inferior quality of little value and stability.
Now I have found that by employing my improved process of treating the materials
used and selecting the proper agents and lieat in the manner hereinafter described I
am enabled to produce methylated spirit of great body and superior quality more
suitable for the purposes to which it is applied & I can produce it at a much lower cost
than the methylated spirit now produced.
In carrying out my improved process I proceed as follows:-
I take either one or a mixture of the following materials containing starch namely :—
grain, cereals, roots and other vegetable substances which I subject to a process of
disintegration so as to reduce it into as fine a meal as possible. This meal to which I
add a suitable proportion of wood also in a disintegrated state is then diluted with the
requisite proportion of water and mixed together with sulphuric acid in the proportion
of 5 lbs. of acid to every 100 lbs. of meal material & the said mixture is then introduced
into a closed vessel (by preference made of copper or gun metal and capable of
resisting an internal pressure of 100 lbs. to the square inch) in which closed vessel the
said mixture is subjected to a heat or temperature of 300 Fahrenheit for one hour.
The sulphuric acid is then neutralized by carbonate of lime or other suitable agent and
the mixture is then drawn off from the residuum, cooled down to a suitable temperature
and then subjected to fermentation and the spirit produced is then distilled off and
ready for use as methylated spirit.
Another process 1 employ is to subject to the same treatment the amylaceous
substances separately and likewise the wood meal and wood tar also separately and
mix the two separate extracts obtained together into the fermenting tub to undergo
alcoholic fermentation or I treat the amylaccous substances separately, fermenting &
distilling the spirit separately and I proceed in the same manner of treating fermenting
and distilling the spirit obtained from the wood meal and wood tar separately & then
mix the two spirits together according to the rules of the excise.
The bye-product left is then subjected to a process of calcination resulting in the
production of charcoal or they are mixed with nitrates or ammoniac or phosphate of
lime in suitable proportions and thus converted into manure.

page_text: From the foregoing it will be seen that by my improved process I can produce
1. The manufacture of methylated spirit direct from the employment of amylaceous
substances, roots and wood mingled together and
2. The production, from the bye-product, of charcoal or manure of superior quality
& properties.

Improvements relating to the Production and Manufacture
Methylated Spirit and the Treatment of the Bye-products Derived
therefrom.
I ALEXANDRE MANBRÉ Senior of 19 Warwick Terrace Vicarage Lane West Ham
in the County of Essex. formerly of 13 Osborne Terrace Clapham Road in the County
of Surrey, Brewer and Sugar Manufacturer do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to an improved process of manufacturing and producing
methylated spirit direct from amylaceous substances contained in grain cereals, roots,
and other vegetable substances and also from suitable wood and wood iar and the
treatment of the bye products derived therefrom for the production of charcoal and
manure.
By the process hitherto employed methylated spirit is produced. by mixing ordinary
spirit made from grain, cereals, starch, beet-root, and molasses and the bye-products
derived from the rectification of spirit with wood or naptha spirit which is a product
obtained from wood and other kindred materials producing methyl and, acetone.
The object of mixing wood spirit with ordinary spirit is to render it permanently
unfitted for drinking purposes and suitable only for use in the production of varnishes
paints and other similar products and also for heating and lighting purposes.
Methylated spirit. thus produced is often deficient in quality, owing to the
difficulty in effecting a proper combination of both kinds of spirit and it is also costly
to produce.
Potato spirit is from time to time used as a substitute for grain spirit but
owing to its being deficient in body and of easy oxydation and vaporization it
produces varnishes and other goods of inferior quality and of little value as regards
durability.
I have found that by employing my improved process of treating the materials used
and selecting the proper agents and heat in the manner hereinafter described I am
enabled to produce methylated spirit of great body and superior quality more suitable
for the purposes to which it is applied and at a much lower cost than the methylated
spirit now produced..
In carrying out my improved process I proceed as follows:-
1. For the production of methylated spirit I take either one or a mixture of several
or of the whole of the following materials containing starch namely, grain, cereals;
roots and other vegetable amylaceous substances which I subject to a process of
disintegration so as to reduce it into as fine a meal as possible.
This starch meal with which I mix suitable proportions of suitable resinous wood
also either as sawdust or disintegrated into meal is then diluted with a suitable
proportion of water and mixed together with sulphuric acid in the proportion of
from 5 lbs. to 10 lbs. for every one hundred pounds of prepared disintegrated
material employed and the said mixture is then run into a close vessel made of
suitable material and capable of resisting an internal pressure of 100 lbs. to the
square inch in which close vessel the said mixture is subjected to a heat or
temperature of 300° Fahrenheit for about one hour when it will be found that the
starch contained in the materials has been converted into a ferimentable extract.
This fermentable extract is then allowed to run into a suitable vessel in which,

page_text: the sulphuric acid is neutralized by carbonate of lime or other suitable agents
and the neutralized extract is then drawn off from the residuum by filtration or
otherwise, cooled down to a suitable temperature and subjected to fermentation.
The spirit produced is then distilled off and ready for use as methylated spirit.
Another process I employ is to subject the starch meal separately and the wood
meal also separately to the same treatment of heat of 300° Fahrenheit so as to convert
each into fermentable extract separately. I then mix the two separate extracts
together in the formenting vessel in which they are subjected to fermentation
together and the spirit produced is distilled off; or, I convert the starch meal into
a fermentable extract and forment and distill off the spirit produced separately
and proceed in the same manner of converting fermenting and distilling off the
spirit produced from the wood meal also separately and I then mix the two kinds
of spirit together according to the rules of the Excise.
2. For the production of charcoal and manure I subject the bye-products by
preference to powerful hydraulic pressure of from 200 to 300 tons to eliminate
the moisture they contain and the compressed product is then subjected to a
process of disintegration and reduced to a fine ineal which fine meal is then
subjected to a process of calcination resulting in the production of charcoal-or,
the said fine meal is mixed with suitable proportions of manurial products such as
phosphates, nitrates, ammonia &c. and thereby rendered most valuable and suitable
as a manure.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
Firstly. The production of methylated spirit direct from the treatment of amylaceous
substances and wood mixed together substantially as herein described.
Secondly. The improved process for treating the amylaceous substances and wood
separately and subjecting the two extracts obtained mixed together to the process of
fermentation and distillation substantially as hersin described.
Thirdly. The improved process for treating the amylaceous substances and wood
separately and subjecting the two extracts obtained to fermentation separately and
distilling off the two kinds of spirit separately and finally mixing them together
substantially as herein described.
Fourthly. The improved process of subjecting the materials used to the high degree
of heat of 300° Fahrenheit for obtaining the complete conversion of the starch they
contain into a fermentable extract thereby obtaining a larger proportion of spirit
substantially as herein described.
Fifthly. The improved process of using a closed vessel constructed of suitable
material and capable of resisting an internal pressure of from 90 to 100 lbs. pressure
to the square inch to allow of obtaining the temperature of 300° Fahrenheit substan-
tially as herein described.
Sixthly. The improved process employed by me of treating the bye products for the
production of charcoal and manure substantially as herein described.
