Uses:
         Furfuryl alcohol is an important organic chemical raw material, mainly used to produce various furan resins, furfuryl alcohol resins and phenol resins. Tetrahydrofurfuryl alcohol may be prepared via hydrogenation, and is a good solvent for varnish and pigments, as well as a rocket fuel. Furfuryl alcohol can further be used for synthesizing fibers, rubber, agrochemicals and in casting.

Uses:

          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 with the use of thiourea dioxide.
          As 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 red uction cleaning of disperse dyes, stripping undesirable colors from dyes, and in dye vat cleaning.
         Thiourea dioxide is also used in the paper industry as a bleaching agent and for deinking waste paper.
         Other uses:Thiourea dioxide 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.
