Description
феннлсулъфид до сих пор получалс 1 ду способов, которые требуют при )ни сложных, исходных материалов и 6 дают неудовлетворительные вы .Fennulsulide has so far produced 1 methods that require complex raw materials, and 6 give you unsatisfactory.
к, дифенилсуАьфид можно получить еванием в запа нной трубке дифенили (CeHslaHg с серой до 23и° (Kraft, IS, Ber. 27, 1771), взаимодействием 1лдиазочи с (NH)2S (Graebe, Mann, Deutsch Chem. Ges. 15, 1683), нагре ем дефенилсульфона с серой (Kraft, iter, Ber. 26, 2815) Можно получить несколькими способами из тиофенола, шмер, взаимодействием тиофенол та и с иодбензолом в присутствии меди ithner, Ber. 39, 8594). В предлагаемрм ;обе дифенилсульфид получаетс взаи;йст1 ием хлорбензола с водным сернистого натри при темпера , 300-370° и соответственно повыном давлении.K, diphenylsulfide can be obtained by diphenyl diphenyl in a sealed tube (CeHslaHg with sulfur up to 23 ° C (Kraft, IS, Ber. 27, 1771), by reacting 1 diazoch with (NH) 2S (Graebe, Mann, Deutsch Chem. Ges. 15, 1683 ), heat of diphenylsulfone with sulfur (Kraft, iter, Ber. 26, 2815). It can be obtained in several ways from thiophenol, schmer, by reaction of thiophenol and with iodobenzene in the presence of copper ithner, Ber. 39, 8594). In the proposed case, both diphenylsulfide is obtained by interaction; chlorobenzene with aqueous sodium sulfate at a temperature of 300–370 ° and correspondingly high pressure is obtained.
Реакци идет по уравнению: 2СбНбС1 + Ма25 (СвН5)25 + 2ЫаС1The reaction proceeds according to the equation: 2SbNbS1 + Ma25 (SvH5) 25 + 2YaC1
Пример: 112,5 г хлорбензола (2 мол ) и 500 слс 8% раствора Na2S (1 моль) иагреваютс несколько часов до температуры 350-360° во вращающемс стальном автоклаве под давлением 170 ат. По окончании нагревани слой дефенилсульфида отдел етс и дифенилсульфнд очищаетс перегонкой. Продукт почети полностью,перегон етс при 290°. Выход хороший. Дифенилсульфид может найти применение как средство дл флотации и в качестве исходного матернала дл синтезов .Example: 112.5 g of chlorobenzene (2 mol) and 500 sls of 8% Na2S solution (1 mol) are heated for several hours to a temperature of 350-360 ° in a rotating steel autoclave under a pressure of 170 at. At the end of the heating, the layer of diphenylsulfide is separated and the diphenylsulfnd is purified by distillation. The product of honor is completely distilled at 290 °. The output is good. Diphenylsulfide can be used as a means for flotation and as a starting material for syntheses.
Предмет изобрет е и .The subject invention and.
Способ получени дифенилсульфида, втличающийс тем, что хлорбензол нагревают под давлением с водным раствором сернистого натра.A process for the preparation of diphenylsulfide, which includes the fact that chlorobenzene is heated under pressure with an aqueous solution of sulfurous soda.
