Sulfur Dichloride At Room Temperature

It is produced by partial chlorination of elemental sulfur.

Sulfur dichloride at room temperature.

It is used in organic synthesis and adds chloride substituted thioethers to alkenes. Disulfur dichloride s 2 cl 2 is the most common impurity in scl 2. Separation of scl 2 from s 2 cl 2 is possible via distillation with pcl 3 to form an azeotrope of 99 purity however sulfur dichloride loses chlorine slowly at room temperature. S 8 4 cl 2 4 s 2 cl 2 δh 58 2 kj mol.

Separation of scl 2 from s 2 cl 2 is possible via distillation with pcl 3 to form an azeotrope of 99 purity however sulfur dichloride loses chlorine slowly at room temperature and reverts to disulfur dichloride. Sulfur dichloride can be purified by distillation in the presence of stabilizers. As disulfur dichloride is formed the contents become a golden yellow liquid. Pure samples may be stored in sealed glass ampules which.

The scl 2 must be applied at room temperature as quickly as possible after distillation within one hour. With water the dichloride structures sulfuric corrosive sulfur and a blend of thionic acids h 2 s x o y. Technical grade sulfur dichloride is produced by passing gaseous chlorine into s2cl2 at low temperature until the correct chlorine content is reached. The reaction proceeds at usable rates at room temperature.

In the laboratory chlorine gas is led into a flask containing elemental sulfur.
