С целью одновременного получени фосфида кальци и сероуглерода предлагаетс следующий способ обработки карбида кальци н тисернистым фосфором.In order to simultaneously produce calcium phosphide and carbon disulfide, the following method is proposed for treating calcium carbide with granular phosphorus.
В железный автоклав с индукционным или наровым обогревом загружаетс смесь тонко размолотых и хорошо смешанных друг с другом карбида кальци и п тисернистого фссфора в примерном соотношении 2:1.A mixture of finely milled calcium carbide and fine grained fiber in an approximate ratio of 2: 1 is loaded into an iron autoclave with induction or heating.
Смесь нагреваетс до температуры начала реакции (150-170°), после чего подогрев выключаетс .The mixture is heated to the temperature at which the reaction starts (150-170 °), after which the preheating is turned off.
Температура сплава после подогрева вследствие экзотермичности реакции быстро возрастает, достига величины 650-700° С.The temperature of the alloy after heating due to the exothermicity of the reaction increases rapidly, reaching a value of 650-700 ° C.
Реакци идет по уравнению:The reaction goes by the equation:
бСаС + 2P,S5 2СазР2 + 5CS2 + 7С.bCaC + 2P, S5 2СазР2 + 5CS2 + 7С.

Готовый продукт представл ет собою сплав, состо щий из смеси фосфида кальци и угл . Сплав легко извлекаетс из аппарата в виде блока.The finished product is an alloy consisting of a mixture of calcium phosphide and coal. The alloy is easily removed from the apparatus as a block.
Дл улавливани сероуглерода процесс сплавлени должен проводитьс в герметичной аппаратуре в токе азота.To trap carbon disulfide, the fusion process must be carried out in a sealed apparatus in a stream of nitrogen.
Сероуглерод выдел ют охлаждением газов в холодильнике.Carbon disulfide is released by cooling the gases in a refrigerator.
Предмет изобретени Subject invention
Способ получени фосфида из карбида кальци и фосфоросодержащих соединений, отличающийс тем, что с целью одновременного получени фосфида кальци и сероуглерода сплавл ют карбид кальци с п тисернистым фосфором.A method for producing phosphide from calcium carbide and phosphorus-containing compounds, characterized in that in order to simultaneously produce calcium phosphide and carbon disulfide, calcium carbide is fused with five-grained phosphorus.
