Description

Этот смачиватель выпускаетс  под маркой СВ-103 в виде водного 36-40%-ного раствора, представл ющего собой маслообразную жидкость темно-оранжевого цвета, легкорастворимую в воде в необходпмы.ч д.:1 . полива концентраци х.This wetting agent is marketed under the brand name CB-103 in the form of an aqueous 36-40% solution, which is an oily liquid of a dark orange color, readily soluble in water in the necessary water content: 1. watering concentrations.

Длительна  практика применени  СВ-103 пленочными фабриками вы вила р д недостатков этой формы смачивател , а именно:The long practice of using SV-103 film factories has revealed a number of disadvantages of this form of wetter, namely:

а)В растворе могут содержатьс  нежелательные примеси, снижаюпхие адсорбционные свойства смачивател  (соли непрореагпровавшего малеинового ангидрида, следы исходного углеводорода и пр.).a) The solution may contain undesirable impurities, lowering the adsorption properties of the wetting agent (salts of unreacted maleic anhydride, traces of the original hydrocarbon, etc.).

б)Водный раствор, содержандий 36-40% СВ-103, недостаточна стабилен при хранении в услови х пониженной температуры.b) The aqueous solution, containing 36-40% of CB-103, is not sufficiently stable when stored under conditions of low temperature.

в)Водный раствор СВ-103 имеет рН около 10, что вынуждает пленочные фабрики, при изготовлении рабочих растворов дл  полива, ней№ 1300402c) An aqueous solution of CB-103 has a pH of about 10, which forces film factories to make working solutions for watering, ne. 1300402

г) Транспортирование и хранение водного раствора СВ-103 св зано с прпменением значительного количества стекл нной тары. Описываемый способ получени  кристаллических солей алкенил нтарных кислот, примен емых в качестве поверхностно-активных веществ при поливе фотографических эмульсий, свободен от выщеуказанных недостатков и заключаетс  в том, что, с целью получени  чистого кристаллического вещества, удобного дл  хранени  и транспорта, омыление ангидридовалкенил итарных кислот провод т в среде метилового спирта при температуре 60°, с последующим охлаждением до 20°, отделением соли и ее сущкой.d) The transportation and storage of the CB-103 aqueous solution is associated with the application of a significant amount of glass packaging. The described method of obtaining crystalline alkenyl succinic acid salts used as surfactants in watering photographic emulsions is free from the above disadvantages and consists in the fact that, in order to obtain a pure crystalline substance convenient for storage and transport, the saponification of anhydride alkanyl acid and carried out in the environment of methyl alcohol at a temperature of 60 °, followed by cooling to 20 °, the separation of salt and its essence.

Пример. В четырехгорлую колбу загружают 42,4 г метанола и 8,0 г (100%-ного) чещуйчатого едкого натра, размешивают до полного растворепи  и при 60° ввод т по капл м в течение одного часа 28 г смгси ангидридов алкенил нтарных кислот со средним мол. весом не ниже 280-285, выдержива  еще один час при 60°. рН реакционной массы 8-9 (по универсальной бумажке). Далее реакционную массу охлаждают до 20° и фильтруют па воронке Бюхнера. Отфильтрованный продукт тщательно отжимают и сущат при 50° до содержани  летучих не выще 0,3%. Выход сухого смачивател  25 г или 73,5% от теоретического.Example. 42.4 g of methanol and 8.0 g (100%) of caustic soda are charged into a four-necked flask, stirred until completely dissolved, and at 60 ° are introduced dropwise within one hour 28 g of smgsi alkenyl succinic anhydrides with an average a pier weighing no less than 280-285, keeping another hour at 60 °. The pH of the reaction mass is 8-9 (according to the universal paper). Next, the reaction mass is cooled to 20 ° and filtered through a Buchner funnel. The filtered product is carefully pressed and dried at 50 ° until the volatile content is higher than 0.3%. The yield of dry wetting 25 g or 73.5% of theoretical.
