Description
Известен способ получени гипса путем взаимодействи хлористого кальци с разбавленной серной кислотой.A known method for producing gypsum by reacting calcium chloride with dilute sulfuric acid.
С целью улучшени качества получаемого продукта и расширени сырьевой базы взаимодействию подвергают дистилл рную жидкость содового производства и серную кислоту , содержащую органические примеси, например примеси производства хлорвинила и хлорэтила.In order to improve the quality of the product and expand the raw material base, distillate soda liquor and sulfuric acid containing organic impurities, for example, vinyl chloride and chloroethyl production, are subjected to interaction.
Наличие органических примесей в кислоте позвол ет получать гипс однородного гранулометрического состава и использовать его в качестве наполнител .The presence of organic impurities in the acid makes it possible to obtain a gypsum of uniform particle size distribution and use it as a filler.
Химические компоненты, % Согласно ГОСТ 4013-61 гипс отвечает требовани м первого сорта.Chemical components,% According to GOST 4013-61 gypsum meets the requirements of the first grade.
Пример. К 250 мл дистиллерной жидкости , содержашей 120 г/л СаСЬ, 55 г/л NaCl, СаСОз, Mg(OH)2, Са(ОН)о при посто нном перемешивании приливают 105 мл 30%-ной отработанной серной кислоты, содержащей органические примеси, в частности примеси производства хлорвинила и хлорэтила.Example. To 250 ml of distiller liquid, containing 120 g / l of CaCl, 55 g / l of NaCl, CaCOz, Mg (OH) 2, Ca (OH) O, with constant stirring, add 105 ml of 30% waste sulfuric acid containing organic impurities. , in particular the impurities of production of vinyl chloride and chloroethyl.
Образовавшийс белый осадок CaS042Н2О отфильтровывают и высушивают. Выход продукта при таком соотношении реагируюших веществ 48,2 г.The resulting white precipitate, CaS042H2O, is filtered off and dried. The product yield at this ratio of reacting substances 48.2 g
Состав полученного двуводного гипса представлен в таблице.The composition of the obtained dihydrate gypsum is presented in the table.
Содержание расчетное 25 лотои, отличающийс тем, что, с целью улучшени качества получаемого продукта и расщирени сырьевой базы, взаимодействию подвергают дистиллерную жидкость содового производства и серную кислоту, содерл ашую органические примеси, нанример примеси проThe estimated content of 25 lots, characterized in that, in order to improve the quality of the product obtained and the expansion of the raw material base, the distiller soda production liquid and sulfuric acid, containing organic impurities, are subjected to the interaction,
