Description
В ОСНОВНОМ авт. св. № 76792 описан снособ выделени перхлорвнннловой смолы из органнческих растворителе(1 под 1закуумом ч водно среде.BASIC Auth. St. No. 76792 describes a method for isolating a perchlorine resin from an organic solvent (1 under 1 vacuum of an aqueous medium.
Предлагаемый способ выделени нер.хлорвиниловон смолы имеет следуюш,1е преимущества: перхлорвиниловую смолу получают в виде неслинаюш.ихс крупинок, практически свободны.х ог влаги и раствори тел , что исключает процесс сушки смолы н сокращает расход пара мл процесс высаживани смолы.The proposed method for the isolation of non-chlorovinyl chloride resin has the following advantages: the perchlorovinyl resin is obtained in the form of non-slender grains, practically free of moisture and solvent, which eliminates the process of drying the resin and reduces the consumption of steam and ml of resin recovery.
Отлнчительной особенностью предлагаемого способа вл етс высаживание смолы путем распыленн раствора вод ным паром в вакуумкамеру .The distinctive feature of the proposed method is the precipitation of the resin by spraying a solution of water vapor into a vacuum chamber.
Высаживание перхлорвиниловой слюлы по новому способу производ т следующим образом: раствор с содержанием 10-12% перхлорвиниловой смолы нагревают до 80-100 и паровой форсункой распыл ют камере при вакууме 500-700 .нм рт. ст.; прп этом температура в камере не должна быть ниже температуры растворител . Смола в камере выпадает в виде мелких крупинок и выводитс из камеры, а смесь паров растворител и вод ного пара поступает в поверхностный барометрпческий конденсатор, на выходе из которого конденсат раздел ют во флорентийском сосуде на растворитель и воду.The perchlorovinyl slyula is planted in a new way as follows: a solution containing 10–12% perchlorvinyl resin is heated to 80–100 and a steam nozzle is sprayed into the chamber under a vacuum of 500–700 nm. Mercury. v .; This temperature in the chamber should not be lower than the temperature of the solvent. The resin in the chamber falls out in the form of small grains and is removed from the chamber, and the mixture of solvent vapors and water vapor enters the surface barometric condenser, at the outlet of which the condensate is separated into a solvent and water in a Florentine vessel.
Предмет изобретени Subject invention
Способ выделени перхлорвпннловой смолы осаждением из хлорбензильного раствора в вакууме но авт. св. № 76792, о т л и ч а ю ш и ii с тем, что высаживание смолы осуп ествл ют расг1ыленнем раствора вод ным на ром в вакуум-камеру.A method for isolating perchlorphine resin by precipitation from a chlorobenzyl solution in vacuum no aut. St. No. 76792, that is, that the precipitation of the resin was made possible by the expansion of the solution of water into the vacuum chamber.
