Title: A process for preparing pure inactive menthol
IPC: C07C35/12
Filed: 1929-12-06
Abstract: Pure inactive menthol is prepared by subjecting the hydrogenation products of thymol, menthones and menthenones or the isomerization products of inactive isomeric menthols to partial esterification, purifying the resulting esters by crystallization and then saponifying.  The partial esterification process frees the starting material from neomenthol, whilst the subsequent crystallization step eliminates isomenthol.  According to the examples, (1) thymol is hydrogenated, the product heated with insufficient phthalic anhydride for complete esterification and then distilled with steam to remove the unesterified menthol fraction consisting chiefly of neomenthol; the remaining ester is recrystallized twice from alcohol and finally saponified; (2) inactive neomenthol is heated with sodium and the isomerization product, after being steam distilled, then esterified with phthalic anhydride as before; on adding alcohol to the mass, the acid phthalic acid ester of inactive menthol crystallizes out; this is twice recrystallized from alcohol and then saponified. Specifications 289,125, 289,126 and 297,019, [all in Class 2 (iii), Dyes &c.], are referred to.

Title: Improvements in the production of black tea concentrates
Inventor: PERECH RAMON
IPC: A23F3/16
Filed: 1956-10-01
Abstract: Tea concentrate is produced by extracting comminuted, unprocessed grean tea leaf by percolation with steam or boiling water, immediately barring the access of air to the solution and evaporating the solution under vacuum to the required consistency after which it is exposed to the air and heated to a temperature of about 80 DEG  to 90 DEG  C. until the essential oils, flavour and aroma are developed. Before heating in the air 0.03 to 0.6% by dry weight of potassium permanganate may be added as an oxidizing catalyst.  In Example 1, 100 lbs. of comminuated unprocessed tea leaf is percolated by steam or boiling water.  The solution is immediately concentrated under vacuum to the required consistency after which the concentrate is oxidized by heating at a temperature of 80 to 90 DEG  C. exposed to the normal atmosphere. According to Example 2, the same process is carried out using 0.03 to 0.06% of potassium permanganate as an oxidation catalyst. Specification 794,566 is referred to.
