摘要： The invention comprises a process for producing a chitosan derivative, and a product prepared thereby, by activating chitosan or a chitosan precursor chitin in alcohol that contains water from 0% to maximum of about 30% and preparing derivatives by reacting with a reagent to get derivatives that have various uses including an antimicrobial, or a microbiostatic, or an antitranspirant, or an antifungal, or a fruit preservative properties or as carrier of active molecules or functional groups etc. or a combination thereof. Illustrated derivatives include acid, succinic, enzymatically deacetylated, enzymatically hydrolysed by chitinolysis, sugar, formaldehyde, phosphoric acid, hydrochloric acid and copper sulfate derivatives that are obtained by reaction individually or in a combination of consecutive reactions. A novel class of thermostable proteo-chitinase is also disclosed prepared from Aspergillus niger MTCC 5572 that has molecular weight on SDS PAGE of about 50 Kilo Daltons and optimum hydrolytic activity at pH 2 and 80° C. Compositions for treatments of natural products and methods for retarding ageing, improvement of shelf life and retarding microbiological spoilage of banana and other fruits are also disclosed.

摘要： This invention comprises a process and a system thereof comprising apparatuses for developing multi-component vapor mixture by heating of solution of reactants comprising one or more of diphenols, or diphenol derivatives, and an organic compound, wherein the organic compound is one which upon reacting in a vapor state in presence of a catalyst with diphenols, or diphenol derivatives, produces a monoalkyl ether of a dihydric phenolic compound; and wherein the entire solution of reactants completely transforms into a super-heated multi-component vapor using heaters without the use of thin film evaporator. The complete transformation of the entire solution of said reactants in to super-heated multicomponent vapor is achieved by heating the entire solution firstly by a pre-heater followed by further heating by a super-heater, further comprising removal of the unevaporated or condensed high boilers and tar to drain, and subjecting the superheated vapor to vapor phase reaction mediated by catalyst to get monoalkyl ether of a dihydric phenolic compound.
