Introduction:
Thiourea dioxide or thiox is an organosulfur compound that is used in the textile industry. It functions as a reducing agent. Thiourea dioxide is not a dioxide, but instead is a derivative of a sulfinic acid(RS(O)(OH), hence the alternative name formamidine sulfinic acid.
Application:
(1) Thiourea dioxide is used in reductive bleaching in textiles.Thiourea dioxide has also been used for the reduction of aromatic nitroaldehydes and nitroketones to nitroalcohols.
(2) Thiourea Dioxide is a new environmental-protection agent which can be used in place of sodium hydrosulfite, It has better thermal stability and stronger reducing ability. Operation is simple and effective, and transportation and storage convenient. There is no pollution associated during the operation.
(3) It is a promoter used with textiles and dyes, it is widely used to reduce dyes and sulfur dyes, and for bleaching wool and silk. Other uses include the reduction cleaning of disperse dyes, stripping undesirable colors from dyes, and in dye vat cleaning.
(4) It is also used in the paper industry as a bleaching agent and for deinking waste paper.
(5) It may be used as catalyst for producing synthetic resins in the polymer materials industry, and also has applications in organic synthesis of photosensitive materials, pharmaceuticals, spices and other fine chemicals, as well as in precious metal recovery and separation.
