Specification
The systematic name of Ethyl tellurac is 3,3-bis[(diethylcarbamothioyl)sulfanyl]-N,N,6-triethyl-1,5-dithioxo-2,4-dithia-3lambda~4~-tellura-6-azaoctan-1-amine. With the CAS registry number 20941-65-5 and EINECS 244-121-9, it is also named as Carbamodithioic acid, diethyl-, tetrakis(anhydrosulfide) with thiotelluric acid. The classification codes are Agricultural Chemical; Fungicide, bactericide, wood preservative; Mutation data; Tumor data. It is orange-yellow to bright yellow fluffy powder which is probably combustible and sensitive to prolonged exposure to light. When heated to decomposition it emits very toxic fumes.
The other characteristics of this product can be summarized as: (1)#H bond acceptors: 4; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 16; (4)Polar Surface Area: 242.52 Å2; (5)Melting Point: 108-118 °C; (6)Density: 1.44 g/cm3.
Uses of Ethyl tellurac: It can be used to improve the rate of vulcanization. It is also used in manufacturing of gasbags ,hoses and insulating layer of electrical wire.
