Embodiment 1

[0055] With 282g soybean oil fatty acid and 270g oleyl alcohol, add in the reactor, add p-toluenesulfonic acid catalyst, pass N 2 Protect under the surface of the reaction liquid, and act as agitator with water, and react at 140-160°C for 2 hours to obtain synthetic cetyl oil with an acid value of 1.33 mgKOH / g. Cool the resulting synthetic cetyl oil to about 60°C, add 98g of maleic anhydride, heat up, stir, and pass N 2 protection, control the reaction temperature at about 200°C, react for 3.5 hours, and then lower the temperature to about 70°C to obtain maleic anhydride-modified synthetic cetyl oil. Add 185g of epichlorohydrin, control the reaction temperature at 80-95°C, react for 3h, and recover excess epichlorohydrin. Then add 300 g of triethanolamine, control the reaction temperature at 50-70° C., and react for 2 hours to obtain a cationic synthetic cetyl oil fatliquoring agent.

[0056] After testing, the cationic synthetic cetyl oil prepared in this example is a reddi...

Embodiment 2

[0058] Add 282g linseed oil fatty acid and 270g oleyl alcohol into the reactor, add an appropriate amount of p-toluenesulfonic acid catalyst, pass N 2 Protect under the surface of the reaction liquid, and act as agitator with water, and react at 140-160°C for 3 hours to obtain synthetic cetyl oil with an acid value of 1.10 mgKOH / g. The resulting synthetic cetyl oil is cooled to 70°C, 98g of maleic anhydride is added, the temperature rises and the reaction is stirred, and the N 2 Protect, control the reaction temperature at 200°C, react for 3 hours, and lower the temperature to 70°C to obtain maleic anhydride-modified synthetic cetyl oil. Add 185g of epichlorohydrin, control the reaction temperature at 80-95°C, react for 3h, and recover excess epichlorohydrin. Then add 180g of triethylamine, control the reaction temperature at 50-70°C, react for 2-4h, and recover the excess triethylamine with a rotary evaporator to obtain a cationic synthetic cetyl oil fatliquor.

Embodiment 3

[0061] Add 280g oleic acid and 270g oleyl alcohol into the reactor, add an appropriate amount of p-toluenesulfonic acid catalyst, pass N 2 Protect under the surface of the reaction liquid, and act as agitator with water, and react at 140-160°C for 3 hours to obtain synthetic cetyl oil with an acid value of 1.13 mgKOH / g. The gained synthetic spermaceti oil is cooled to about 70 ℃, adds 90g maleic anhydride, heats up and stirs reaction, and passes N 2 Protect, control the reaction temperature at 200°C, react for 3.5 hours, and lower the temperature to 75°C to obtain maleic anhydride-modified synthetic cetyl oil. Add 185g of epichlorohydrin, control the reaction temperature at 80-95°C, react for 3h, and recover excess epichlorohydrin. Then add 300g of triethanolamine, control the reaction temperature at 50-70°C, and react for 2-4h. A cationic synthetic cetyl oil fatliquor is obtained.

Abstract

The invention provides cationic synthetic sperm oil fat liquor and a preparation method thereof. In the fat liquor, synthetic sperm oil, maleic anhydride, epichlorohydrin and quaternization reagent are used as raw materials, maleic anhydride modified synthetic sperm oil is obtained by addition reaction of the synthetic sperm oil and the maleic anhydride; the maleic anhydride modified synthetic sperm oil is added with the epichlorohydrin, and reacts with the quaternization reagent to prepare the cationic synthetic sperm oil fat liquor. By adopting an internal emulsification method, a cationic active group is introduced to the molecular structure of the synthetic sperm oil, so the stability of the emulsion, uniformity and permeability of the fat can be greatly improved, and the cationic synthetic sperm oil fat liquor has better effects of dyeing, burnishing and color fixing than that of the cationic fat liquor by the traditional external emulsification method.

Description

technical field [0001] The invention relates to a preparation method of a cationic fatliquoring agent, which belongs to the technical field of leather chemical industry. Background technique [0002] Sperm oil, also called whale brain oil, is a natural marine animal oil. Its components not only contain triglycerides of fatty acids, but also contain more long-chain alcohol esters of higher fatty acids, namely cetyl esters. , also contains some free higher alcohols. Wherein cetyl ester accounts for about 85%, wherein unsaturated cetyl ester accounts for about 70% of cetyl ester. The unique chemical structure of spermaceti oil not only endows the leather with softness, plumpness, and strong oily feeling, but also makes the leather have a waxy feel, which is not available in other fatliquoring agents. However, because whales are rare and protected animals that are on the verge of extinction in the world, the hunting of whales in various countries has made the resources of natu...
