Description
Technical Field
The invention relates to a preparation method of solvent yellow 33, belonging to the technical field of chemical dye preparation.
Background
Solvent yellow 33 is an ideal colorant for various plastics, is widely applied to coloring materials such as daily plastics, bobbin materials, industrial grease, paint ink, color master batches and the like at present, and is also suitable for coloring spinning yarns of chemical fibers, terylene, nylon, acetate fibers and the like. It is also useful for the coloration of alcohol-soluble varnishes, PES, PC, polyesteramines, acrylics, cosmetics and fumes, and occasionally for the coloration of hydrocarbon solvents.
The main synthesis technology at present is to use 2-methylquinoline and phthalic anhydride to react, and (anhydrous) zinc chloride is used as a dehydrating agent to participate in the reaction. For example, as disclosed in the prior art "Lehrbuch der Organischen Chemie, veit and Co., leipzig,1913, vol.1, part 2, p.1360", a preparation method is provided, in which phthalic anhydride is used in an excess amount of 5 times the mole of 2-methylquinoline, the phthalic anhydride is used as both a reaction raw material and a reaction solvent, and anhydrous zinc chloride is added as a dehydrating agent, and the reaction is carried out at 180 to 190 ℃ for 4 hours to produce 2- (2-quinolyl) -1H-indene-1, 3 (2H) -dione, and although the excess phthalic anhydride (melting point of 131 ℃) is added to increase the fluidity of the reaction solution, the phthalic anhydride is solidified when the reaction solution is cooled to room temperature after the reaction is completed, and the treatment is very inconvenient. The great excess phthalic anhydride cannot be recovered, and the cost is also seriously increased. US1963374 discloses a preparation method in which o-dichlorobenzene is added as a reaction solvent and anhydrous zinc chloride is also used as a dehydrating agent, which solves the problem of fluidity of the reaction solution, but the reaction temperature is only 180 ℃ at most due to the limitation of the boiling point (180 ℃) of o-dichlorobenzene, and finally the reaction time is 20 hours or more. In addition, the addition of o-dichlorobenzene as a reaction solvent also increases the solvent recovery cost. In both methods provided above, anhydrous zinc chloride is used, but since zinc chloride readily absorbs water, it becomes very cumbersome to prepare anhydrous zinc chloride. Furthermore, CN103073919A discloses a solvent yellow 33 which, although anhydrous zinc chloride is not used, also employs zinc chloride as a reactant to form a mixture. The zinc chloride is used for participating in the reaction, and in order to ensure the ash content index in the final product, a large amount of water is needed for washing, so that waste and pollution are caused. Meanwhile, 2-methylquinoline is used as a solvent, so that the conversion rate of raw materials is not high, and the single output is low.
Disclosure of Invention
Based on the defects of the prior art, the invention provides a preparation method of solvent yellow 33, which does not use zinc chloride, does not generate solid base waste and wastewater, and adopts a dropwise adding mode to carry out reaction, thereby effectively solving the problems of raw material conversion rate and pollution waste.
In order to solve the problems, the invention adopts the following technical scheme:
a method of preparing solvent yellow 33, the solvent yellow 33 having the reaction formula:
the preparation method comprises the following specific steps:
step 1: weighing phthalic anhydride and adding the phthalic anhydride into a reaction container;
step 2: heating to the reaction temperature, dropwise adding 2-methylquinoline, and controlling the temperature of the system to be not lower than 185 ℃ during dropwise adding;
and step 3: after the dropwise addition is finished, preserving the heat for 1-3h at 190-240 ℃;
and 4, step 4: gradient cooling, wherein a high-boiling-point solvent is added in the cooling process, and the material is transferred and filtered after the temperature is reduced to room temperature, so as to obtain a wet product;
and 5: and (4) washing the wet product formed in the step (4) by using an organic solvent, and drying to obtain a qualified product.
Further, zinc chloride is not used as a dehydrating agent to participate in the reaction in the method.
Further, the mass ratio of the 2-methylquinoline to the phthalic anhydride to the high-boiling solvent is 1:0.9 to 1.2:5.0 to 5.1.
Further, the boiling point of the high boiling point solvent in the fourth step is not lower than 190 ℃.
Further, in the step 5, the organic solvent is methanol, ethanol, acetone and xylene.
The invention has the beneficial effects that:
according to the preparation method provided by the invention, the reaction is carried out in a dropwise adding mode, theoretically, 100% conversion of the 2-methylquinoline and the phthalic anhydride can be realized, and no raw material waste exists. The used high boiling point solvent can be repeatedly used, and no solvent is wasted. The reaction time is short, and the single reaction yield is high. No zinc chloride is used, and no solid base waste and waste water are generated. The obtained product has the purity of more than 98 percent, no ash and the like, and has remarkable advantages and effects compared with the prior art.
