Abstract:
PURPOSE: A yellow azo disperse dye is provided to obtain the same concentration of color even from a small amount of dye when dying because of excellent lightproof, inside sublimability, dispersability, and a high molar extinction coefficient, is also environmentally friendly, and reduces the production costs. CONSTITUTION: A yellow azo disperse dye is indicated as chemical formula 1. In the chemical formula 1, A is selected from the compounds from the chemical formula 1-a. R1-R3 are respectively selected from hydrogen, hydroxyl group, amide group, nitro group, acetyl group, C1-6 alkyl group, C1-6 haloalkyl group, C1-6 alkoxy group, C6-14 aryl group and SO2R7. R4-R6 is respectively selected from hydrogen, C1-6 alkyl group, C1-6 halo alkyl group, C1-6 alkoxy group, nitro group or halogen group. R7 is selected from C1-6 alkyl group, C1-6 alkylamine group, and C6-14 arylamine group or C1-6 acetoxyalkyl group.

본 발명은 극세사 염색용 황색 아조 분산염료 및 그의 합성법에 관한 것이다. 보다 더 구체적으로 자동차 내장재에 적합한 극세사 염색용 황색 아조 분산염료와 그의 합성법에 관한 것이다. 본 발명에서 제조된 황색 아조 분산염료는 내광성, 내승화성 및 분산성이 종래의 염료들 보다 우수하고, 몰 흡광계수가 종래의 분산염료보다 1.7배 정도 높아 염색 시 염료의 사용량을 적게 하여 같은 농도의 색상을 얻을 수 있으므로, 환경친화적일뿐만 아니라, 생산가격을 절감 하는 효과를 얻을 수 있다.
Abstract:
PURPOSE: A manufacturing method of 2-t-butyl hydroquinone is provided to reuse unreacted hydroquinone and a solvent and to facilitate manufacture of a high quality butyl hydroquinone and butyl hydroxy anisole. CONSTITUTION: A manufacturing method of 2-t-buyl hydroquinone comprises a step of adding hydroquinone and phosphate to an organic solvent and stirring the mixture; a step of adding a tert-butanol or isobutene to the reaction mixture and conducting a reaction; a step of filtering solid of the reaction mixture to separate unreacted hydroquinone; a step of separating phosphate from the filtrate; and a step of separating and purifying t-butyl hydroquinone and unreacted hydroquinone which are the product of a reaction mixture.
