Description
Примен емые методы переработки листьев, стебл и других частей каучуконосного растени ваточника путем экстрагировани и центрифугировани направлены к получению только лишь одного продукта - так называемого смолистого каучука. Содержащиес в перерабатываемых част х белковые и в одоэкстр активные вещества при этих методах тер ютс .The applied methods of processing leaves, stems and other parts of the rubber plant of the sprat by extraction and centrifugation are directed to the production of only one product - the so-called resinous rubber. The protein and odextr active substances contained in the processed parts are lost with these methods.
В интересах использовани этих веществ и более полного разделени смол ной и каучуковой фракций предлагаетс перерабатывать вегетативную массу ваточника путем последовательной селективной экстракции трем растворител ми.In the interest of using these substances and more fully separating the resin and rubber fractions, it is proposed to process the vegetative mass of the vatochnik by sequential selective extraction with three solvents.
Измельченное сырье экстрагируют водным раствором щелочи, полученный остаток обезвоживают и экстрагируют сначала амиловым или бути .ловым спиртом дл извлечени смол, а затем дихлорэтаном дл извлечени каучука.The crushed raw material is extracted with an aqueous solution of alkali, the residue obtained is dried and extracted first with amyl or butyl alcohol to remove the gums, and then with dichloroethane to remove the rubber.
Остаток после щелочной экстракции может быть экстрагирован дихлорэтаном; в этом случае каучукоОтв . редактор М. М. Акишин 13 Свод в. 7.The residue after alkaline extraction can be extracted with dichloroethane; in this case, rubber. editor M. M. Akishin 13 Code in. 7
ва фракци осаждаетс из экстракта амиловым или бутиловым спиртом .The wa fraction is precipitated from the extract with amyl or butyl alcohol.
Выделение смол ной и каучуковых фракций может быть осуществлено гидродестилл цией, а удаление из экстрагируемой массы воды и спирта - отгонкой азеотропных смесей.The extraction of resin and rubber fractions can be carried out by hydrodestillation, and the removal of water and alcohol from the extracted mass by distillation of azeotropic mixtures.
