Embodiment 1

[0032] Polydimethylallyl (2-benzoyl-5-n-butoxyphenyl) ammonium bromide synthetic route is:

[0033]

[0034] 1) Synthesis of 3-n-butoxytoluene

[0035] Add 10.8g of m-cresol, 11.2g of potassium hydroxide, 4.0g of potassium iodide and 120ml of absolute ethanol in a 250ml dry three-necked flask, and when the water bath is heated to 80°C, slowly add 28ml of bromobutane dropwise with a dropping funnel, The reflux reaction was continued, and TLC was tracked and detected until the reaction was completed. A large amount of solid appears, add 80ml of distilled water to dissolve it, transfer the reaction solution into a separatory funnel, separate the upper organic layer, wash twice with distilled water, extract the remaining organic phase in the aqueous phase with ethyl acetate, and combine the two For the organic phase, use a rotary evaporator to distill off the crude product of the solvent. The crude product was separated and purified by flash column chromatography to obtain a ...

Embodiment 2

[0075] A color-fixing agent containing an ultraviolet absorbing group, the color-fixing agent is made by adding the prepared polydimethylallyl (2-benzoyl-5-n-butoxyphenyl) ammonium bromide After mixing in a mixed solvent of ethanol and distilled water, the pH of the system is adjusted to neutrality to obtain the product. The product is a light yellow transparent liquid (hereinafter referred to as "self-made auxiliary agent"). Wherein, the ratio of the polydimethylallyl (2-benzoyl-5-n-butoxyphenyl)ammonium bromide to the mixed solution is 1g: (10-20) ml: the mixed solution The ratio of ethanol and distilled water is 1: (1~2).

[0076] Performance Testing

[0077] 1. Test results of basic performance indicators of self-made additives

[0078] Test the color-fixing performance of self-made auxiliaries and commercial color fixing agents to investigate whether the self-made auxiliaries can meet the actual application requirements. Observe the appearance of the self-made auxilia...

Abstract

The invention discloses a poly-dimethylallyl (2-benzoyl-5-n-butoxypolyethylene phenyl) ammonium bromide synthesis method and a dye-fixing agent. According to the method, a molecule is acquired by the aid of a chemical synthesis mode and contains reactive groups, quaternary ammonium salt groups, ultraviolet absorbing groups, benzophenone groups and double-bond groups, the double-bond groups are polymerized to obtain a macromolecular compound containing more than two functional groups, a structure of a synthesis substance is represented, and the macromolecular compound is used for the dye-fixing agent (dyeing and finishing additive) of reaction dye dyeing processes. The dye-fixing agent saves energy, reduces emission and consumption on section of dye-fixing processes, sunlight fastness and ultraviolet protection factors of dyed fabrics can be improved, a common commodity dye-fixing agent does not have the performance, the comprehensive dye-fixing effect of the dye-fixing agent reaches or is superior to that of the commodity dye-fixing agent, so that the dye-fixing agent has high practical values and can be effectively applied to enterprise production.

Description

technical field [0001] The invention belongs to the dyeing technical field of printing and dyeing auxiliaries, in particular to a synthesis method of polydimethylallyl (2-benzoyl-5-n-butoxyphenyl) ammonium bromide and a color-fixing product containing the compound agent. Background technique [0002] Due to the destruction of the earth's ozone layer, the radiation of ultraviolet rays in the sun to the earth is enhanced. Therefore, the research and application of related ultraviolet substances are becoming more and more extensive. Benzophenone compounds have a large π-conjugated system, low toxicity, and good light stability. In polymers, they can convert absorbed energy into heat energy or release harmless low-radiation energy to protect their from damage, it is considered a good UV absorber. However, the traditional method of synthesizing benzophenones has problems such as complicated methods, many by-products, low yield, and environmental pollution; and the use of cataly...
