Title: A process for the preparation of di-esters
IPC: C07C69/28
Filed: 1948-08-06
Abstract: Diesters of alpha-omega dihydroxyalkenes or alkanes containing at least four carbon atoms with carboxylic acids are made by pyrolysing triesters of alpha, beta, omega-trihydroxyalkanes of at least four carbon atoms, to give the alkene diesters, which may be hydrogenated to the alkane diesters.  The diols may be obtained by saponification. The pyrolysis may be carried out continuously or batchwise, at 300-650 DEG  C., in liquid or vapour phase. Carboxylic acids specified are acetic, propionic, butyric and valeric and preferably have 2-8 carbon atoms.  Inert materials may be in the pyrolysis zone, and also catalysts, e.g. activated alumina or carbon, calcium phosphate, acidic calcum and silicon phosphates.  Hydrogenation catalysts used may contain nickel, vanadium, palladium, platinum, copper, chromium, iron, cobalt, ruthenium, molybdenum, tungsten, iridium, silver, or their oxides and sulphides.  Small proportions of diolefinic monoesters may be formed in the pyrolysis stage.  An example describes the pyrolysis of 1.2.6-hexanetriol triacetate, to give principally hexenediol diacetate, which is hydrogenated with a Raney nickel catalyst to give hexamethylene glycol diacetate, which is saponified with sodium in methanol to give hexamethylene glycol.

Patent GB-202985-A (GB)
IPC: C01B15/00
Filed: 1923-08-20
Abstract: The materials, such as sodium carbonate or hydrate, borax &c from which persalts are to be prepared are first treated with a reagent to remove any metal compound which might act catalytically upon the finished product so as to cause liberation of oxygen.  The reagent is allowed to act for a sufficient time, such as several days, to ensure that the impurity, which may be in colloidal solution, shall precipitate, and the precipitate is removed by filtration.  The reagents mentioned as suitable are alkali monosilicates and disilicates.  In the examples a solution of borax and caustic soda is treated with sodium disilicate Na2 Si2 O5 and allowed to stand for two or three days at 30-35 DEG  C.  The filtered solution is cooled to 0-5 DEG  C. and hydrogen peroxide is added, the perborate being precipitated. Sodium carbonate solution is purified in a similar manner, filtered, and treated with hydrogen peroxide at 0-5 DEG  C. for the production of the percarbonate.  Persalts prepared in this manner are stable and do not need the addition of protective substances.ALSO:The materials, such as sodium carbonate or hydrate, borax &c from which persalts are to be prepared are first treated with a reagent to remove any metal compound which might act catalytically upon the finished product so as to cause liberation of oxygen.

[Class 144 (i)] Consists of a method of and apparatus for the manufacture of pneumatic tyres whereby the building operations are initiated manually by an attendant at one station and the - succeeding operations are performed automatically in a predetermined cyclic order and in timed relation at a series of stations provided with fabricating devices. The apparatus comprises six building drums A, B ... F, Fig. 1, mounted on a rotatable shaft 13 whereby each drum may be brought into co-operation with any of six fabricating stations, I, II ... VI, the rotation of the apparatus being effected by the downward motion of an hydraulic cylinder 53 to which is secured a rack 55 which meshes with a ring gear 56 fixed to the outer disc of the drum carrying device 15. Each drum is rotated, when positioned at a fabricating station by an electric motor 69. The building operations are initiated by an attendant at station I, which is provided with means for collapsing the tyre-forming drums, to allow of the removal of the completed tyres, and for returning the drums to their normal shape, and also with means which actuate rack-bars 34, 35, Fig. 2, for moving ply-supporting members 25 into or out of operative relation with the drums. Devices 89, 90, for applying cement to each edge of the drums are provided at stations II and III, respectively, in addition to stitching devices 103, 104, for stitching the plies over the edges of the drums. Further stitching devices 94, 117, are located above the drums at stations II and III, respectively, the former for stitching down the first two fabric plies along the drum edges and the latter for uniting the plies and tread transversely of the drums. Station IV is provided with mechanism for operating the head-setting devices 36, Fig. 2, and comprises hydraulically actuated arms 137 which engage with a peripheral groove 39 in the left-hand device 36 and with a similar groove 45 in a spring-controlled member 44 by which the right-hand device 36 is actuated.
