Title: Improvements in or relating to manufacture of substituted o-nitro amino compounds
Inventor: LANE EDWARD SYDNEY
Filed: 1954-05-01
Abstract: A process of preparing a substituted o-nitro-amino compound comprises converting the corresponding substituted amine to the alkali metal salt of the N-nitro derivative and effecting the rearrangement of the salt in an acid medium to form the o-nitro-amino compound.  The substituted amine may be nitrated in a potassium ethoxide solution, e.g. containing ethanol and diethyl ether, using an alkyl nitrate. The potassium salt of the N-nitro derivative is allowed to separate out and is then added portionwise to dilute aqueous sulphuric acid. In examples: 3-nitro-o-anisidine is obtained by treating o-anisidine with a mixture of potassium ethoxide ethanol, diethyl ether and amyl nitrate, adding the potassium salt of o-anisylnitramine which separates to aqueous sulphuric acid and neutralizing the reaction mixture, after dilution, with ammonia (1); and 4-chloro-2-nitro aniline is similarly obtained using p-chloraniline as starting material.

Title: Improved process relating to the manufacture of borneol
IPC: C07C35/30
Filed: 1928-05-02
Abstract: 311,085. Austerweil, G. May 2, 1928. Borncol is obtained by heating nopinene with an organic acid anhydride and slowly adding alcohol to produce nascent organic acid which reacts with the nopinene to form a bornyl ester. The process can be carried out under pressure and preferably in the presence of a solvent, such as toluene, xylene, or pinene, which does not react with the nascent acid. Example :-Nopinene and phthalic anhydride dissolved in pinene or xylene are heated to 145‹ C. and ethyl alcohol is added drop by drop. The mass is further heated under a reflux condenser and is then cooled and poured into a solution of sodium carbonate. After driving off the solvents from the upper layer a residue of bornyl-ethyl-phthalate is obtained from which borneol is obtained by saponification. The alcohol may be recovered by saponification and distillation and phthalic anhydride may be recovered from the sodium phthalate by treatment with mineral acid and heating the phthalic acid so obtained.

Filed: 1960-04-13
Abstract: The substance "butyrospermol", i.e. 3b -hydroxy-(13a , 14b , 17b H)-lanosta-7,24-diene, is extracted from "shea-butter" (the kernels of the fruit of the W. African tree butyrospermum Parkii) with CCl4. The fatty materials obtained by evaporation of the solvent are taken up by sodium hydroxide dissolved in pure methanol and the methanol is removed to give a soap which is put on a chromatographic column which is extracted with CHCl3. Evaporation of the solvent gives a mixture of the triterpene alcohols butyrospermol, b -amyrin and "Parkeol" (3b -hydroxy-lanosta-9(11), 24-diene) which is acylated by acetic anhydride in the presence of pyridine and the acetates separated by fractional crystallization or by chromatography on alumina. Pure butyrospermol may then be obtained by hydrolysis of its acetate.ALSO:Pharmaceutical compositions for oral, parenteral and local application, e.g. as tablets, parenteral solutions, balms and ointments and having hormonal, cicatrizing and bactericidal activity comprise a carrier and the compound butyrospermol having the structure <FORM:0932662/VI/1> The butyrospermol may be extracted from the kernels of the fruit of butyrospermam Parkii (shea butter) or the oil mill cakes thereof or from the latex of the breadfruit tree.  The extraction from shea-butter is described wherein the raw material is ground with CCl4, and the solvent is removed from the extracted fatty materials which are taken up in NaOH/CH3OH.  The methanol is removed and the resultant soap is put in a chromatographic column which is extracted with CHCl3.  By evaporation of the solvent a mixture is obtained comprising butyrospermol, b -amyrin and "Parkiol" which may be used in the formulation of the compositions or the butyrospermol extracted therefrom (see Group IV (b)).
