| titleOfInvention | Preparation method of orange surfactant |
| abstract | A preparation method of orange surfactant takes nonionic surfactants with different HLB values as raw materials, and the chloridization reaction is carried out to obtain chloridization products of intermediate nonionic surfactants, and the chloridization products and sodium salt of p-hydroxy azobenzene sulfonate are subjected to substitution reaction to synthesize a series of nonionic surfactant azobenzene sulfonate with different structures; they have the characteristic structures of surfactants and azo dyes; these orange-yellow products are readily soluble in water and are surface active. |
