Description
В насто щее врем производство вискозы состоит из р да отдельных операций: мерсеризаци , измельчение, ксан тогениривание, растворение. Насто щее изобретение имеет целью сокращение производственного цикла и усовершенствование операции ;ксантогенировани , техническое оформление которой в насто щее врем страдает с -щественными недостатками, из которых основной-недостаточна равномерность процесса и получаемого продукта. Обычный метод сульфидировани замен етс в данном случае обработкой . алкалицеллюлозы эмульсией сероуглерода. В качестве эмульгатора можно примен ть мыло или раствор вискозы.Можно вести процесс получени ксантогената также в обратном обычному пор дке: сначала обработать целлюлозу эмульсией сероуглерода, после чего добавить необходимое количество раствора крепкого едкого натра, при дальнейпгем размешивании получить ксантогенат, a после добавлени необходимого количества воды в том аппарате получить готовую вискозу. Currently, the production of viscose consists of a number of individual operations: mercerization, grinding, xanogenesis, dissolution. The present invention aims to shorten the production cycle and improve the operation, xanthogenation, the technical design of which currently suffers from significant drawbacks, of which the main is the lack of uniformity of process and the product obtained. The conventional sulfiding method is replaced in this case by treatment. alkaline cellulose carbon disulfide emulsion. Soap or viscose solution can be used as an emulsifier. The xanthate can also be prepared in the reverse normal order: first treat cellulose with carbon disulfide emulsion, then add the required amount of caustic soda solution, with xanthate after further mixing, water in the machine to get ready viscose.

В полученную эмульсию погружаетс 70 г целлюлозы. Смесь при охлаждении обрабатываетс 132 г NaOH 47° Be в течение 1 часа. Дл растворени образовавшегос ксантогената добавл ют 525 см воды. Весь процесс проводитс в одном аппарате.70 g of cellulose is immersed in the resulting emulsion. The mixture is cooled and treated with 132 g of NaOH 47 ° Be for 1 hour. To dissolve the xanthate formed, 525 cm of water are added. The whole process is carried out in one apparatus.
Пример 2. 70 г целлюлозы замачивают в 320 г NaOH , в смесь добавл ют эмульсию о.ероуглерЧда состава: 3 г мыла олеинового бО°/о-го в 30 гм воды. 20 г сероуглерода и 20 г бензина хорошо размешивают в течение 2 часов.
