CARBON DISULFIDE - (75-15-0)

Introduction

Name: carbon disulfide
* IUPAC
CAS Number: 75-15-0
Chemical Formula: CS2
Molar Mass: 76.1407 g
Mass Percent: C 15.774 %; S 84.225 % 

Classification

• inorganic

Uses/Function

• "Carbon disulfide is used to manufacture rayon and cellophane. For this purpose, cellulose from wood is dissolved chemically in sodium hydroxide and carbon disulfide to give a syrupy solution called viscose. The viscose is extruded into an acid bath, where the cellulose is regenerated as a textile fiber (rayon) or a film (cellophane)." 1
