Chemistry expert, please answer. What industries are thiourea dioxide, sodium percarbonate, furfuryl alcohol and furfural used in? It would be better to explain it in detail.

Thiourea dioxide is a substitute product of sodium hydrosulfite, which has the characteristics of strong reducibility, good thermal stability and convenient storage and transportation. This product can be used as reducing agent, bleaching decolorant, plastic stabilizer, organic synthetic antioxidant and effective agent for photosensitive materials. It has been widely used in printing and dyeing, papermaking and other industries, and there is no pollution during use.

(1). The printing and dyeing industry can be used as reducing agent, bleaching reducing agent for cotton, wool and chemical fiber, reducing agent for sulfur dyes, printing disperse dyes, decoloring textiles, reprocessing or decoloring.

(2) Used for pulp bleaching in paper industry.

(3) When used as emulsifier in camera industry, the exposed part of photographic paper can show high stability.

(4) The chemical fiber modification catalyst can make the modified fiber yellow.

(5) As an antioxidant in organic synthesis.

It is an important organic chemical raw material. Mainly used in the production of furfural resin, furan resin, furfuryl alcohol urea-formaldehyde resin, phenolic resin and so on. It is also used to prepare fruit acid, plasticizer, solvent and rocket fuel. In addition, it is also widely used in dye, synthetic fiber, rubber, pesticide and foundry industries. Furfural is a raw material for preparing many drugs and industrial products. 1, 6- hexamethylenediamine [H2n-(CH2) 6-NH2] prepared from furfural is the raw material for preparing nylon 66.

Furan made from furfural can also be made into butyraldehyde by electrolytic reduction, which is the raw material for the production of atropine. Many derivatives of furfural have strong bactericidal ability. Furfural is mainly used as a solvent, which can selectively extract unsaturated components from petroleum and vegetable oil, as well as aromatic components from lubricating oil and diesel oil. Furfural can be condensed with phenol instead of formaldehyde to produce phenolic resin.
