Summary:
the present invention relates to an improvement in the synthesis process of dispersed red 92. the dispersed red 60 is used as the raw material, chlorosulfonic acid is used as the sulfonation reagent, chlorosulfonation is carried out with thionyl chloride after sulfonation, and the two-step reaction is still completed in a bath. after the reaction, ice water is added for separation and filtration, the filter cake is washed with cold water, and then mixed with the condensing agent;-Ethoxypropylamine) reaction to produce the finished product; this process uses thionyl chloride as the chlorosulfonation reagent, which improves the reaction activity, reduces the reaction temperature, reduces the coking of the material in the reaction process, and improves the product quality. The reaction yield is greatly improved; the condensation process uses water instead of & gamma in the original process;-methoxypropylamine (or & gamma;-ethoxypropylamine) as the reaction medium, the economic benefits are considerable.

Lumacron Red BLSFP - Study on the purification of high purity C.I. Disperse red 92
From Wanfang
Author:
Ma Ying, Xing Ying, Li Wenxiao, Cong Linquan
Summary:
A purification method of C.I. Disperse Red 92 was studied. Disperse Red 92 original dye is dissolved and filtered in solvent and alkali solution, and the purified product is obtained by acidification process. The solvent is acetone, the concentration of alkali solution is 10%, the dissolution temperature is 60~65 ℃, the yield can reach more than 90%, and the chromatographic content of purified product can reach more than 98.5%.

national and provincial code:
CN320412
Summary:
The present invention relates to the field of fine chemicals, and specifically relates to a method for synthesizing dispersed red 92, which includes the following steps: adding dispersed red 60 solid into an inert solvent for dissolution; adding chlorosulfonic acid and thionyl chloride to the dispersed red 60 solution, Heat preservation for sulfonylation reaction; after the sulfonylation reaction is completed, add sodium carbonate until the reaction solution is neutral; then add sodium carbonate and ethoxypropylamine for heat preservation, the material is filtered and washed with water to obtain the finished product of dispersed red 92. Compared with the prior art, the present invention has the advantages of greatly reducing the amount of chlorosulfonic acid, reducing the discharge of waste acid and excessive chlorosulfonic acid in the dilution process to produce a large amount of hydrogen chloride gas emissions; changing the original two-step operation into One-step operation simplifies the production process; one-step filtration and water washing process is missing, which reduces the loss of materials in the intermediate operation process and improves the product yield.

Lumacron Red BLSFP - Reference Information
| LogP | 1.88 at 20℃ |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | disperse red FBL is used for dyeing and printing polyester and its blended fabrics, with blue light red and excellent dyeing fastness. Suitable for high temperature and high pressure dyeing and hot melt dyeing. |
| Production method | Using 1-aminoanthraquinone and 4-hydroxy-N-ethoxypropylbenzenesulfonamide as raw materials. The former is first halogenated (chlorinated or brominated), hydrolyzed to obtain 1-amino-4-hydroxy-2-halogenated anthraquinone, and then condensed with the latter to obtain the product. The finished product is filtered, ground and dried.. |
