Getting

Heating a mixture of phosphorus pentachloride and diphosphorus pentasulfide :

{\mathsf {3PCl_{5}+P_{2}S_{5}\ {\xrightarrow {120^{o}C}}\ 5PSCl_{3}}}

{\ displaystyle {\ mathsf {3PCl_ {5} + P_ {2} S_ {5} \ {\ xrightarrow {120 ^ {o} C}} \ 5PSCl_ {3}}}}

Heating a mixture of sulfur and phosphorus trichloride ^[2] :

{\mathsf {S+PCl_{3}\ {\xrightarrow {130^{o}C,AlCl_{3}}}\ PSCl_{3}}}

{\ displaystyle {\ mathsf {S + PCl_ {3} \ {\ xrightarrow {130 ^ {o} C, AlCl_ {3}}} \ PSCl_ {3}}}}

The reaction of hydrogen sulfide and phosphorus pentachloride :

{\mathsf {H_{2}S+PCl_{5}\ {\xrightarrow {}}\ PSCl_{3}+2HCl}}

{\ displaystyle {\ mathsf {H_ {2} S + PCl_ {5} \ {\ xrightarrow {}} \ PSCl_ {3} + 2HCl}}}

Physical Properties

Thiophosphoryl trichloride forms a colorless liquid, smoking in air, with the smell of hydrogen sulfide.

It is soluble in carbon disulfide , benzene , carbon tetrachloride .

Chemical Properties

Slowly hydrolyzed with water:

{\mathsf {PSCl_{3}+4H_{2}O\ {\xrightarrow {}}\ H_{2}S+3HCl+H_{3}PO_{4}}}

{\ displaystyle {\ mathsf {PSCl_ {3} + 4H_ {2} O \ {\ xrightarrow {}} \ H_ {2} S + 3HCl + H_ {3} PO_ {4}}}}
