Description
Предметом насто щего авторского свидетельства вл етс способ получени хлористого бари и сероводорода из технического плава сернистого бари и отбросных щелоков хлористого кальци , получаемых при производстве бертолетовой соли.The subject of this author's certificate is a method of obtaining barium chloride and hydrogen sulfide from technical melt of barium sulphate and waste liquor of calcium chloride, obtained in the manufacture of potassium chlorate.
Этот способ отличаетс от известных тем, что в первой стадии процесса технический плав сернистого бари обрабатываетс таким количеством раствора хлористого кальци или щелока, полученного во второй стадии процесса, чтобы половина всего содержащегос в плаве BaS перещла в BaClj, а остальна часть в Ba(SH)2.This method differs from the known ones in that in the first stage of the process the technical melting of the barium sulphide is treated with such an amount of calcium chloride solution or lye obtained in the second stage of the process so that half of the BaS contained in the melt is transferred in BaCl1 and the rest in Ba (SH) 2
Процесс в первой стадии основан на реакцииThe process in the first stage is based on the reaction

Раствор, содержащий хлористый барий и сульфгидрат бари , отстаиваетс или отфильтровываетс и смешиваетс с таким количеством отбросного щелока от производства бертолетовой соли, чтобы в образовавщемс щелоке наThe solution containing barium chloride and barium sulfhydrate is settled or filtered and mixed with such amount of waste liquor from the manufacture of potassium chlorate, so that in the resulting liquor on

Полученный щелок подвергаетс действию чистой или разбавленной воздухом COj при температуре 80-100°, причем получаетс в растворе BaCI и в осадке СаСОз-по реакции Ba(SH)2 + СаСЬ + COj + НоО - Bad, + + CaCO,+ H2SThe obtained liquor is exposed to pure or diluted air with COj at a temperature of 80-100 ° C, and it is obtained in a BaCI solution and in a CaCO3 precipitate by the reaction Ba (SH) 2 + CaCI + COj + Ho - Bad, + + CaCO, + H2S
в осадок проходит небольшое количество побочно образовавшегос BaCOj.a small amount of BaCOj formed as a precipitate passes into the sediment.
Получившийс раствор содержит BaCU и СаСи в количестве от 0,5 до 1 мол. СаОг на мол.

BaCl2. Under the specified process control, the release of HgS is 2 mol. on 1 mol. introduced carbon dioxide.
Хлористый барий может быть выделен из раствора в виде BaClj 2 HjO кристаллизацией, либо с применением выпарки, либо высаливанием добавочным количеством раствора хлористого кальци . Отделенный от кристаллов BaCIj 2 HjO маточный щелок, содержащий CaCh и незначительное количество ВаС возвращаетс в первую стадию процесса.Barium chloride can be isolated from the solution in the form of BaCl j 2 HjO by crystallization, either by evaporation or salting out with an additional amount of calcium chloride solution. Separated from BaCIj 2 HjO crystals, mother liquor containing CaCh and a small amount of BaC returns to the first stage of the process.
Предлагаемый способ существенно отличаетс от способа, описанного герм. пат. № 28062 1883 г., тем, чтопроцесс ведетс в две стадии, причем в первую стадию к техническому плаву BaS добавл етс половина эквивалентного количества CaClj, чем достигаетс образование Са(ОН)2, переход щего в осадок, удал емый со шламом, расход углекислоты соответственно сокращаетс , концентраци , соответственно повышаетс . ... 1 Кроме того, в предлагаемом способе примен етс отбросный CaClj от производства бертолетовой соли, имеющий примесь КСЮд, котора , вл сь активным окислителем, вызывает во всех случа х применени щелока CaClj сильнейшую коррозию аппаратуры, в данном же случае берт.олетова соль окисл ет эквивалентное количество HgS, чем устран етс oifiaCHucTb коррозии.The proposed method differs significantly from the method described by the germs. pat No. 28062 of 1883, in that the process proceeds in two stages, and in the first stage half of the equivalent amount of CaClj is added to the technical melt of BaS, thus achieving the formation of Ca (OH) 2, which passes into the sludge removed with sludge, carbon dioxide consumption correspondingly reduced, the concentration increased accordingly. ... 1 In addition, in the proposed method, waste CaCl1 from the production of bertolet salt is used, which has an admixture of CSWD, which, being an active oxidizing agent, causes in all cases of the use of liquor CaClj the strongest corrosion of the apparatus, in this case bertolite salt oxidizes an equivalent amount of HgS, thus eliminating oifiaCHucTb corrosion.
