Abstract
The currying agent for leather is mainly formed from the following one or more of amine oxide phosphate compounds in which phosphonation rate is 6-96% (mole), and the oxidation rate of tertiary amine nitrogen is 0-90% (mole). Said invention also provides the structural formula of said currying agent, and possesses good currying effect, dyeing-improving and level dyeing action, can promote absorption of said currying agent and its anchoring power with heather fibre, and is a low fogging property and laundry-proof currying agent.
Description
The present invention is both sexes leather fat and the preparation method that a class process hides is used, and it belongs to the organic synthesis and the preparation of natural fats and oils and fatty acid ester modifier.
The phosphoric acid ester fatting agent has good flexibility, and the sense of finished leather mercerising is strong, and water resistance is good, the biodegradable of phosphoric acid ester especially, and to preserving the ecological environment, it all is very favourable advocating the process hides cleaning technique.Therefore, phosphate aster leather currying agent has been subjected to the great attention of domestic and international process hides circle, and based on different material, the synthetic new product of developing emerges in an endless stream.But with the phosphoric acid ester is the amphoteric leather fat of anion-radicals, and report seldom.
The first patent of oxidative amination compound is published in nineteen thirty-nine, but just causes people's attention after the sixties.Because N → O group is a strong polar group in the amine oxide, cloud density trend oxygen atom, it is cation in acid medium, then is nonionic in neutrality and alkaline medium.Long chain amine oxide is main in process hides is used to embody surface oil lubricant nature, strong water absorbability and to the sorbency of anionic dyestuff, stuffing material.1994, German patent DE 4312972 was reported the application method of fatty amine oxide as the leather coloring auxiliary agent, showed that dyestuff penetration is dark, was evenly distributed, help dye effective.
The objective of the invention is a synthetic class ammonium oxide phosphate aster leather currying agent, integrate the advantage of amine oxide and phosphoric acid ester two compounds; Give leather simultaneously and have soft feel, surface oil moisture feeling, mercerising sense, water-repellancy, help and dye level-dyeing property, and the readily biodegradable of fatting agent own, good by the leather absorptivity, the few characteristics of residual volume in the waste liquid.
Leather fat of the present invention is based on following two kinds of parent compounds:
Wherein: R=C
2～C
20Alkyl, alkylene;
X+y=2～10, x and y can equate, also can not wait;
z=1～4。
Parent compound III and IV after the neutralization, are used H through phosphorylation reaction again
2O
2Oxidation, so that the phosphorylation rate of an OH base is 6～96% (moles) in III and the IV, the oxygenation efficiency of tertiary amine nitrogen is 0～90% (mole), thereby obtains leather fat of the present invention, its chemical structural formula is I and II:
Wherein: R=C
2～C
20Alkyl, alkylene;
X+y=2～10, x and y can equate, also can not wait;
z=1～4：
M is H or Na, K, NH
4 +And organic amine, M can be one of them, also can be wherein two kinds, perhaps wherein three kinds.
Ammonium oxide phosphoric acid ester leather fat agent prescription of the present invention consists of: I 0～60% (weight, down together), and II 0～60%, solvent 5%～15%, surplus is a water.
Wherein solvent is the trimethyl carbinol.
Gained leather fat of the present invention, its concrete course of reaction is: respectively parent compound III and IV are dropped into reactor, start and stir and the heat temperature raising fusing, add solvent tertiary butanol, slowly add phosphorylation agent P again
2O
5, in 60～80 ℃ of lower reactions 3～6 hours, add the neutralization bases aqueous solution, being neutralized to the pH value is 7～8, slowly adds H again
2O
2Liquid continues 70～90 ℃ of lower reactions 2～4 hours, and cooling discharge gets leather fat of the present invention.
Wherein neutralization bases is Na, K and NH
+ 4Oxyhydroxide; Organic amine is thanomin, diethanolamine, trolamine.
Parent compound III and IV are a class fatty acid ester and fatty acid amide compound, are the commercial goods, maybe can be synthetic by prior art.
The leather fat good emulsion stability of the present invention's preparation, anti-dielectric medium is the both sexes leather fat of a class stuffing wide adaptability.It can also promote other negatively charged ion fatting agent, the absorption of anionic dyestuff, help that to dye the level dyeing effect strong, because group N → O forms the very capable of hydrogen bond, phosphate radical also can with the collagen mortise, so leather fat of the present invention and hide fiber binding ability are strong, belong to ground fog, laundry-resistant fatting agent kind.
