Patent GB-714378-A (GB)
Title: Improvements in or relating to activated silica
IPC: B01J20/10
Filed: 1952-06-04
Abstract: Activated silica is obtained by precipitating silica at ambient temperature from an alkali metal silicate by means of an organic acid washing the silica with water, drying below 250 DEG C., activating by boiling with a solution of an organic acid having a concentration of 5 per cent. by weight or less washing again with water and drying below 250 DEG C.  Acetic acid is preferred for both preparation and activation but tartoric or sulicylic acids may be used.  The alkalic metal silicate, preferably sodium, may be prepared by the action of the corresponding base on silicon tetrafluoride and thus be iron-free.  After use, for example, as an absorbent of hormones, the silica may be reactivated by boiling with an aqueous solution of an alkali metal hydroxide having a concentration of 5 per cent. by weight or less, and activating with the organic acid as above.

Title: Process for the manufacture of laevo-ascorbic acid
IPC: C07D307/62
Filed: 1936-05-21
Abstract: Laevo-ascorbic acid (Vitamin C) is prepared by heating esters of the bismethylene ethers of 2-keto-laevo-gulonic acid with acid agents such as hydrochloric acid, sulphuric acid, potassium bisulphate, oxalic acid or formic acid.  The type of alcohol used in the esterification of the bismethylene ethers is not important, basic and neutral esters yield equally satisfactory results.  In examples: (1) Diacetone-2-keto-laevo-gulonic acid allyl ester is hydrolyzed with 18 per cent hydrochloric acid for 10 minutes, neutralized and evaporated to dryness.  The residue is extracted with methyl alcohol from which the laevo ascorbic acid crystallizes; (2) diacetone-2-keto-laevo-gulonic acid diethylaminoethyl ester is hydrolyzed with hydrochloric acid and worked up as in example (1). Specifications 425,198 and 428,815 are referred to.

Patent GB-442061-A (GB)
Title: Process for the preparation of vanillin
IPC: C07C47/58
Filed: 1935-05-17
Abstract: Vanillin is obtained from a eugenol-containing oil, e.g. clove oil or cinnamon oil, by heating the oil with caustic potash in less than 24 minutes to over 225 DEG  C., preferably while stirring and with the addition of paraffin hydrocarbons.  The potassium iso-eugenate is then dissolved in water, separated from the hydrocarbon, and subsequently oxidized with nitrobenzene at a temperature above 115 DEG  but below 145 DEG  C.  The oxidation is carried out so that the concentration of the reaction mixture changes, i.e. volatile products are distilled off, and preferably the recovered oil from a previous oxidation is added to the reaction mixture.  The reaction mixture (at approximately 120 DEG  C.) is added to hot water, kept at 95 DEG  C. for a short time, and quickly cooled to 18 DEG  C.  The solid vanillin is filtered off, washed with benzene, redissolved in hot water and filtered.  The solution is then cooled to 18 DEG  C. and acidified with acetic acid, and the crude vanillin recrystallized with the aid of active carbon. Further quantities of vanillin are recovered from the reaction solution.  The water content of the mixture during the oxidation preferably varies from three times the eugenol-containing oil at the beginning to about one tenth of the oil at the end.
