PROVISIONAL SPECIFICATION...
A Process for Obtaining Lactyl Compounds Derived from Methyl-
aniline, Ethyl-aniline, P-anisidine and P-phonetidine.
I GEORGE WILLIAM JOHNSON of 47 Lincoln's Inn Fields, in the County of
London, Patent Agent do hereby declare the nature of this invention (which has
been communicated to me from abroad by The Chemische Fabrik, late Goldenberg,
Geromont & Co. of Winkel on the Rhine in the German Empire) to be as
follows:-
This invention relates to improvements in the process described in the Specifica-
tion of the prior British Letters Patent numbered 12166 and bearing date the
30th day of June 1892.
According to this invention for the purpose of deriving lactyl compounds from
methyl-aniline, ethyl aniline, p-anisidine and p-phenetidine, amide of lactic acid
may be employed instead of, the lactic acid, anhydride of lactic acid, lactide or
lactic acid ether referred to in the said prior British Patent No. 12166 of 1892,
and it will prove equally advantageous.
The following example will illustrate how this invention may be performed; the
parts being by weight.
8-9 parts of lact-amide are heated with 13.7 parts of p-phenetidine in an open
vessel, to a temperature of 150° Centigrade, until the mixture ceases to evolve
ammonia. The said mixture is then allowed to cool down to 105° Centigrade, and,
after this, poured into hot diluted hydrochloric acid. After cooling lactyl-para-
phenetidine will crystallize out.
Dated the 16th day of October 1894.

1, GEORGE WILLIAM JOHNSON of 47 Lincoln's Inn Fields in the County of
London, Patent Agent, do hereby declare the nature of this invention (which has
been communicated to me from abroad by The Chemische Fabrik late Goldenberg
Geromont & Co. of Winkel on the Rhine, in the German Empire) and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to improvements in the process described in the Specifica-
tion of the prior British Letters Patent numbered 12166 and bearing date the
30th day of June 1892.
According to this invention for the purpose of obtaining lactyl compounds from
methyl-aniline, ethyl-aniline, p-anisidine, and p-phenetidine; amide of lactic acid
is employed instead of the lactic acid, anhydride of lactic acid, lactide, or lactic
acid ether, referred to in the said Specification of the prior Eritish Patent
No. 12166 of 1892, and it will prove equally advantageous.

page_text: The following example will illustrate how this invention may be performed; the
parts being by weight.
8.9 parts of lact-amide are heated with 13.7 parts of p-phenetidine (or methyl-
aniline, ethyl-aniline, or para-anisidine) in an open vessel, to a temperature of
15. Centigrade, until the mixture ceases to evolve ammonia. The said mixture is
then allowed to cool down to 10° Centigrade, and after this, is poured into
hot diluted bydrochloric acid. After cooling, lactyl-para-phenctidine will
crystallize out.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is -
In the manufacture of lactyl compounds from methyl-aniline, ethyl-aniline, para-
anisidine, and para-phenetidine, by the process the subject of British Letters Patent
12166 the substitution of amide of lactic acid for the lactic acid, anhydride of
lactic acid, lactide, or lactic acid ether, mentioned in the Specification of that
Patent.
Dated this 15th day of July 1895.
