Description
При обычном способе пригото- 1 влени сиккативов обменным раз- j ложением натровых мыл с сол ми сиккативных металлов отмывание получающегос пластыр от натрового мыла и др. солей представл ет I большие затруднени , так как при- ; ходитс примен ть многократное | промывание водой с последующим | удалением ее высушиванием или ; выпариванием.IIn the usual method of preparing shikkativov by the exchange decomposition of sodium soaps with siccative metal salts, washing the resulting patch from sodium soap and other salts represents a great difficulty, since it is; It is necessary to apply multiple | washing with water followed by | removing it by drying or; evaporation. I
Предлагаемый способ пригото- влени сиккативов основан на известном приеме осаждени пла- . стырей и разбивани мыльной i эмульсии путем прибавлени солей 1 нещелочных металлов. По этому I способу осевщий резинат или линолеат , увлекший натровое мыло и | воду, не промываетс и не высушиваетс . После полного выделе- i ни осадка воду сливают, не забо- т сь о тщательном отделении ее. Мокрый осадок, содержащий увлеченное натровое мыло, раствор етс в скипидаре или в другом растворителе , в результате чего получаетс смесь из скипидарного и водного растворов, котора легко распадаетс на два сло . Водный слой вл етс отбросом, скипидарный же - представл ет собою сиккатив, который загр знен водной эмул.ьсией натрового мыла. Эмульси эта очень устойчива и наличность ее делает такой сиккатив непригодным в качестве товара. Эмульси очень быстро и полно разрушаетс , если скипидарный раствор размещивать с сол ми каких-либо металлов, кроме щелочных. Лучше, если эти соли растворимы в воде, например, CaCI-, ZnSO, ZnCl.j и др. Их действие об сн етс тем, что вместо натриевого (или калиевого) мыла, которое обусловливает прочную эмульсию, образуетс нерастворимое в воде, но легко растворимое в скипидаре, цинковое, кальциевое или другое мыло. Щелочной же металл, св зыва сь с остатком минеральной кислоты, переходит в водный раствор в виде NaCl или MagSO (KCI или K2SO4 в случае, если имели калийное мыло). Наличность в водном растворе солей обусловливает высаливание и, следовательно , более быстрое освобождение скипидарного раствора от влаги и эмульсии, которое может быть ускорено центрофугированием .The proposed method for the preparation of siccativas is based on the well-known technique of sedimentation. break down and break the soap emulsion by adding salts 1 of non-alkali metals. By this method I sowing resins or linoleate, enticed soda soap and | water is not washed or dried. After complete discharge of the precipitate, the water is drained, without taking care of carefully separating it. The wet sediment containing entrained sodium soap is dissolved in turpentine or in another solvent, resulting in a mixture of turpentine and aqueous solutions, which easily disintegrates into two layers. The water layer is garbage, and turpentine is a desiccant, which is contaminated with water emulsion of sodium soap. This emulsion is very stable and its cash makes such a desiccant unusable as a product. The emulsion is very quickly and completely destroyed if the turpentine solution is placed with salts of any metals other than alkaline. It is better if these salts are soluble in water, for example, CaCI-, ZnSO, ZnCl.j, etc. Their effect is due to the fact that instead of sodium (or potassium) soap, which causes a solid emulsion, it forms water-insoluble but easy turpentine-soluble zinc, calcium or other soap. The alkaline metal, bound to the remainder of the mineral acid, goes into the aqueous solution in the form of NaCl or MagSO (KCI or K2SO4 in the event that it has potassium soap). The availability of an aqueous solution of salts causes salting out and, consequently, faster release of the turpentine solution from moisture and emulsion, which can be accelerated by centrifuging.

Способ приготовлени сиккативов обменным разложением натровыхThe method of preparation of desiccants exchange decomposition of sodium
или калиевых мыл с растворимыми сол ми сиккативных металлов, отличающийс тем, что полученный при обменном разложении осадок, по грубом отделении от водного раствора, раствор ют в скипидаре или в другом органическом растворителе , после отстаивани и удалени водного сло прибавл ют какой-либо соли нещелочного металла , дающей нерастворимый в воде осадок с жирными или смол ными кислотами, и снова удал ют водный слой.or potassium soaps with soluble salts of siccative metals, characterized in that the precipitate obtained during the exchange decomposition, by coarse separation from an aqueous solution, is dissolved in turpentine or in another organic solvent, after settling and removing the aqueous layer, add a non-alkaline salt metal, giving a water-insoluble precipitate with fatty or resin acids, and removing the aqueous layer again.
