Description
Известные способы бисульфитации ванилина, вырабатываемого из лигносульфонатов нутем обработки ванилика-сырца бисульфитом натри , не обеснечивают необходимого качества ванилина и св заны со значительными его потер ми.The known methods of vanillin bisulfite produced from lignosulfonates by treating raw vanilla with sodium bisulfite do not purify the required quality of vanillin and are associated with significant losses.
Предлагаемый способ бисульфитании ванилина устран ет недостаткн сун1,ествуюш.их сиособов тем, что 6iicyjHA)HTauHio ванилина производит в ироцессе его экстракции бенЗО .ЧОМ без предварительной отгонки последнего, чем достигаетс увеличение выхода и улучшение качества ванилина.The proposed method of bisulfite vanillin eliminates the lack of suction of their methods in that 6iicyjHA-HTauHio vanillin produces benzo in the process of its extraction, which results in an increase in yield and an improvement in the quality of vanillin.
Схлциость предлагаемого способа бнсульфитации заключаетс в следуюн| .ем.The complexity of the proposed procedure for sulfation is as follows | .eat.
Беизол1)ный экстракт ванилина по вУз1ходе пз экстрактора, до поступлени в иснлрите.гь подаетс в расnbr .:ieiHiOH виде и проходит через колонку н.чи систему их, наиолненных pficTBopOM бису :и;фнта натрн . При этом ванилин вступает в химическую реакцию с бисульфитом, образу альдегид-бисульфитное соединение, растворимое в воде, аBeizol1) extract of vanillin according to the extract from the extractor, before entering the unit, is delivered to the solution: ieiHiOH in the form and passes through the n.ch system, their system, the pficTBopOM bis, and; In this case, vanillin enters into a chemical reaction with a bisulfite, forming an aldehyde bisulfite compound, soluble in water, and
все другие органические веи;есгва, в том числе 1.рае ш,ие и емолы остаютс в бензольном экстракте и поступают на да,иьнейи1ую циркул цию в экстрактор. Раствор альдегида-бисульфнтно1Х ) соединени посчуиает на дальнейшую переработку , как предусмотрено технологической схемой.all other organic veins; esgva, including 1.rae, si and emols remain in the benzene extract and go to the yes, non-circulation in the extractor. The aldehyde-bisulfate (1X) compound solution appears for further processing, as provided for in the technological scheme.
При осуи;ествлении предлагаемого способа вы.ход ванилина повышаетс за счет того, что бисульфитаци протекает в более разбавленных раство|)ах, а также за счет исключени операции иснарени , ири которой тер етс часть ванилина .With the introduction of the proposed method, vanillin rises due to the fact that bisulphidation proceeds in more dilute solutions, as well as by excluding the surgery and decontamination of which part of the vanillin is lost.
