Description

A kind of application of DISPERSE DYES
Technical field
The present invention relates to a kind of application of DISPERSE DYES.
Background technology
DISPERSE DYES is that a class formation is simple, water-soluble low, mainly with the non-ionic dye that molecule is dispersity existence in dye bath.Just come out as far back as early 1920s, be mainly used in the dyeing of acetate fibre at that time, be therefore also referred to as cellulose acetate dye.In recent years, along with synthetic fiber particularly the developing rapidly of polyester fiber, DISPERSE DYES becomes one of the fastest dyestuff of modern development gradually.Be mainly used in dyeing and the stamp of polyester fiber at present, also can be used for the dyeing of the hydrophobic textile material such as acetate fibre and polyamide fiber.Along with the raising of people's living standard, consumer is also more and more higher for the requirement of weaving official ceremonial dress performance, and as required, dyed textiles has higher fastness to sublimation, the multinomial fastness such as sun-resistant.DISPERSE DYES of some conventional application are as red in C.I. 153, C.I. purple 93, C.I. blue 291 and C.I. orange 288 etc., be then not suitable for requiring higher application to fastness to sublimation.
The reaction of phenol and epoxychloropropane has the introduction of similar structures compou nd synthesis method in US Patent No. 2010279997A1; In addition, be the explanation also having related methods of synthesis in the CAS database of 122-60-1 at No. CAS.But the synthetic method reaction time that above patent document is mentioned is long, post-processing operation is loaded down with trivial details, and needs the participation of a large amount of solvent, very uneconomic environmental protection.
Prepare the reaction of compound 4, in US Patent No. 4448719A, have the introduction of similar structures compou nd synthesis method;
In addition, at document Russian Journal of Organic Chemistry, 43(8), 1176-1179; Also the introduction of dependency structure compound synthetic method is had in 2007.But preparation technology's course of reaction of document report is complicated, and post-processing operation is loaded down with trivial details.
Prepare the reaction of compound 2, there is no patent literature at present, only has the reaction of similar acylated hydroxy, at document Russian Journal of Organic Chemistry, 43(8), 1176-1179, has similar reaction in 2007, but is adopt chloroacetic chloride to carry out acidylate to hydroxyl in the document; Do reaction raw materials with acyl chlorides, toxicity is large, and requirement of shelter is higher, and in last handling process, environmental pollution is serious.
