Specification
Sulfur dichloride is an organic compound with the formula Cl2S, and its systematic name is the same with the product name. With the CAS registry number 10545-99-0, it is also named as Monosulfur dichloride. It belongs to the product category of Inorganics. Its EINECS number is 234-129-0. In addition, the molecular weight is 102.97. It should be sealed and stored in a cool, ventilated and dry place. Moreover, it should be protected from oxides, heat and fire.
Physical properties of Sulfur dichloride are: (1)ACD/LogP: 1.335; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.34; (4)ACD/LogD (pH 7.4): 1.34; (5)ACD/BCF (pH 5.5): 6.09; (6)ACD/BCF (pH 7.4): 6.09; (7)#H bond acceptors: 0; (8)#H bond donors: 0; (9)#Freely Rotating Bonds: 0; (10)Polar Surface Area: 25.3 Å2; (11)Index of Refraction: 1.516; (12)Molar Refractivity: 19.744 cm3; (13)Molar Volume: 65.274 cm3; (14)Polarizability: 7.827×10-24cm3; (15)Surface Tension: 35.83 dyne/cm; (16)Density: 1.578 g/cm3.
Preparation: it is produced by the chlorination of either elemental sulfur or disulfur dichloride. The process occurs in a series of steps. S2Cl2 is the most common impurity in SCl2. Separation of SCl2 from S2Cl2 is possible via distillation with PCl3 to form an azeotrope of 99% purity, however sulfur dichloride loses chlorine slowly at room temperature and reverts to disulfur dichloride. Pure samples may be stored in sealed glass ampules which develop a slight positive pressure of chlorine, halting the decomposition.
S8 + 4 Cl2 → 4 S2Cl2
S2Cl2 + Cl2 → 2 SCl2
Uses of Sulfur dichloride: it is used in organic synthesis. It adds to alkenes to give chloride-substituted thioethers. It is also a precursor to several inorganic sulfur compounds. Moreover, it is used as chlorinating agent in organic synthesis, and it is also used as annexing agent of cutting oil. It can be used as a disinfectant and fungicide.
