Description
До сего времени в качестве отравл ющего вещества против саранчи и других вредителей нримен ли натровую соль мышь ковистой кислоты, содержащую 76°/о-Дз ОзUntil now, mouse acid soda salt, containing 76 ° / o-Dz Oz, was used as a poisoning agent against locusts and other pests.
Предлагаемый снособ получени кислого арсенита натри , имеющий Задачу получёки дл вышеуказанных целей препарата с более высоким содержанием мышь ка, доход щим до 85, , заключаетс во взанмодейст1 ии едкого натра и мыйь ковистой кислоты, вводимых в реакцию в отнощении 1:1, 7-2,7 в растворе, содержащем от 20, воды. Дл заводских целей отношение между обоими, компонентами 1:2,3 нри 307о води дает наиболее благопри тньге выходы соли. Самый процесс о учени арсенита состоит в том, зто «охлажденный до 20°-25° сильно насыщенный мышь ком раствор помешиваетс до выделени мышь ка в виде тонких перышек, обладающих свойством легко обра/гно раствор тьс и образовывать кристаллическую натровую соль мышь ковистой кислоты Na&2(As02) 3, структурна формула которой имеет вид:ОНThe proposed method of obtaining acidic sodium arsenite, which has the Objective of obtaining for the above purposes a preparation with a higher content of arsenic, reaching up to 85, is in the action of caustic soda and mystic acid, introduced into the reaction in relation to 1: 1, 7-2 , 7 in a solution containing from 20, water. For factory purposes, the relationship between the two, 1: 2.3 components at 307 °, gives the most beneficial salt yields. The very process of arsenite learners is that the highly saturated mouse, cooled to 20 ° -25 °, is stirred until the mouse is dispersed as thin feathers, which have the ability to easily dissolve and form the crystalline mouse salt of Na &; 2 (As02) 3, the structural formula of which is: HE

Образование этой соли происходит одновременно с выделением мышь ка, только гораздо медиеннее, а приблизительно через 12 часов весь раствор превращаетс в густую массу, где количество мыщь ка преобладает. По мере выделени кристаллической натровой соли, выпавший/мышь к начинает раствор тьс и выкристаллизовываетс в натровую соль, котора отдел етс от маточного раствора центрофугированием и высушиваетс при температуре не выше 100°. Содержание , в соли достигае 85,84/о. Маточный раствор оп ть идет обратно в производство; к нему при бавл ют столько воды и ,, чтобы были восстановлены отношени , необходимые дл получени указанной кислой соли. Получение очищенной соли достигаетс промыванием соли нри центрофугзЕсровании 50-бО/о-пымч раствором спирта.The formation of this salt occurs simultaneously with the release of the mouse, only much more medioune, and after about 12 hours the whole solution turns into a thick mass, where the amount of the mouse is predominant. As the crystalline sodium salt precipitates, the precipitated / mouse salt begins to dissolve and crystallize into the sodium salt, which is separated from the mother liquor by centrifugation and dried at a temperature not higher than 100 °. Content in salt reaches 85.84 / o. The mother liquor again goes back into production; so much water is added to it, so that the ratios needed to obtain the acid salt are restored. The preparation of the purified salt is achieved by washing the salt with a centrifugal solution of 50-BO / O-pymch with a solution of alcohol.
