Abstract
The invention relates to a synthesis technique improvement of disperse red 191 which takes the disperse red 60 and hexanediol monobenzyl ether of hydioquinone as raw materials, uses potassium carbonate or potassium hydroxide as an acid binding agent and uses an emulsifier of OP series as a catalyst; after the raw materials are condensed at high temperature to the terminal, the product can be segregated by methanol (or ethanol) when the temperature is cooled, and at last the product is filtrated and separated. The mother liquid is rectified to recycle the methanol (or ethanol), phenol and hexanediol monobenzyl ether of hydioquinone, and the technique improves the product quality.
Description
Technical field:
The synthesis technique that the present invention relates to a preparation disperse red 191 (C.I.Disperse Red 191) improves.
Background technology:
Disperse red 191 (C.I.Disperse Red 191) is used for the dyeing and the stamp of terylene and BLENDED FABRIC thereof, light fastness is relatively good, be widely used in the contour shunting yard of automobile institute coloration of textile materials, physical data introduction 1-aminoanthraquinone bromination, hydrolysate and ethyleneglycol monophenylether condensation obtain.But the quality product that obtains of route often can not get the nod thus in actual production.
Summary of the invention:
With disperse red 60, ethyleneglycol monophenylether is a raw material, is acid binding agent with salt of wormwood or potassium hydroxide, is catalyzer with OP series emulsifying agent, and pyrocondensation is behind terminal point, and cooling filters to isolate product with methyl alcohol (or ethanol) product of emanating out.Methyl alcohol (or ethanol), phenol, ethyleneglycol monophenylether are reclaimed in mother liquor rectifying respectively.
Embodiment:
1. in reactor, drop into 600 kg ethylene glycol monophenyl ethers, double centner OP series emulsifying agent, 300 kilograms of disperse red 60s, 150 kg of potassium carbonate.
2. be heated to 130～150 degree, be incubated 6 hours, the some plate is judged terminal point, after terminal point arrives, begins cooling.
3.60 begin to drip 800 kilograms of methyl alcohol (or ethanol) below the degree, added in 2 hours.
4. add, press filtration, washing obtains product, and oven dry obtains 300 kilograms of product.
5. mother liquor reclaims methyl alcohol (or ethanol), phenol, ethyleneglycol monophenylether respectively.
Claims (2)
1, structure as shown in the formula compound.
2, the preparation technology of the compound of claim 1 improves, and it is characterized in that through following steps:
With disperse red 60, ethyleneglycol monophenylether is a raw material, is acid binding agent with salt of wormwood or potassium hydroxide, is catalyzer with OP series emulsifying agent, and pyrocondensation is behind terminal point, and cooling filters to isolate product with methyl alcohol (or ethanol) product of emanating out.Methyl alcohol (or ethanol), phenol, ethyleneglycol monophenylether are reclaimed in mother liquor rectifying respectively.The phenol that reclaims can be used for synthetic disperse red 60, and the ethyleneglycol monophenylether of recovery can be used for synthetic disperse red 191, and the methyl alcohol of recovery (or ethanol) can be used for the segregation of synthetic disperse red 191.
