Description
Technical field
The present invention relates to the preparation method of alkylolamide, alkylolamide, and the method for the storage means of alkylolamide and reduction alkylolamide color and luster.
Background technology
Alkylolamide compounds is the important nonionogenic tenside of a class, and it has good foaming, steady bubble, thickening, decontamination, emulsification, inhibition, the performance such as antistatic.Because of with natural reproducible oil resource for raw material, nontoxic, harmless, biological degradation rate is high and be widely used in many industrial circles such as shampoo, body lotion, washing composition, makeup, lubricant, weaving.According to the difference of raw material, the preparation method of alkylolamide class nonionogenic tenside can be divided into fatty acid process, fatty acid methyl ester process and glycerine ester process.
Fatty acid process refers to and obtains fatty acid ethanol amide with lipid acid and thanomin direct reaction.Although the synthesis technique of the method is simple; but because the acylation reaction of directly carrying out with lipid acid is reversible; so the water that reaction generates must be removed away in time; and the temperature required height of this reaction; by product is more, wayward, comparatively dark (the household chemicals science of product color; 2009,32 (04): 15 ~ 18).Thus, the little producer of part is only had to adopt the method at present.
Fatty acid methyl ester process refers to fatty acid methyl ester to be that raw material and diethanolamine are obtained by reacting product.There is temperature of reaction low; side reaction is few; acid amides transformation efficiency advantages of higher; but technical process is more complicated; cost is higher, and by-product carbinol requires high (Chemical Industry in Guangzhou, 2009 to labour protection, fire prevention, the working condition such as explosion-proof; 37 (4): 34 ~ 42), thus in actual production, a definite limitation is subject to.
Glycerine ester process also can be described as grease method and refers to grease to be that raw material directly synthesizes alkylolamide.Because it has, oil source is extensive, reaction process simple, less investment, low cost and other advantages, and the existing alkylolamide synthesized in this way occupies the larger market share.Also study hotspot is become gradually for raw material adopts glycerine ester process to synthesize alkylolamide at present with natural animal-plant oil.(the Henan chemical industry such as Zhou Furong, 1998, (01): be 18 ~ 19) raw material with purified soyabean oil, at the temperature of 100 ~ 155 DEG C, in the ratio Multistep feeding of n (soybean oil): n (diethanolamine)=1:4.5 ~ 1:5.5, the mode of staged reaction obtains highly purified soybean oil alkylolamide; Wang Duoren (dyeing and printing auxiliary, 2002,10(01): 2 ~ 4), feeds intake by equimolar ratio with refining butter and monoethanolamine, in 60 DEG C of reaction 8h under decompression, catalyst action, obtains tallow acid alkylolamide through acetone recrystallization; Kolancilar (J.Am.Oil.Chem.Soc., 2004,81 (6): 597 ~ 598) be raw material with oreodaphene, catalyzer is made with excessive diethanolamine, cocatalyst is made with the sodium methylate of 0.2 ~ 2%, by the feed ratio of n (oreodaphene): n (diethanolamine)=1:10, at the obtained laurane alcohol amide of room temperature condition reaction; [the J.Am.Oil.Chem.Soc. such as Lee, 2007,84:945 ~ 952] use the mixture of epoxy palm oil and palm-kernel oil temperature of reaction 110 DEG C, react the product that 5h obtains diglycollic amide under the condition of n (diethanolamine): n (grease)=3: 1.Zhejiang Zan Yu company is to after the crude oil direct bleaching of Oleum Cocois, palm-kernel oil, palm wet goods, feed intake by crude oil and thanomin weight ratio 1:0.2 ~ 1.0, batch charging under certain vacuum degree, staged reaction 1 ~ 34h obtain product [Ge Zan etc., CN102153487A].Wherein Oleum Cocois alkylolamide (being commonly called as detergent 6501) is one of most important kind of alkylolamide class nonionogenic tenside.Because Oleum Cocois source is in short supply, mainly rely on import, cost higher, Recent study personnel are finding the substitute of Oleum Cocois always, as Oleum Gossypii semen, soybean oil, rapeseed oil, sweet oil, palm wet goods are all used to alternative Oleum Cocois, but because lipid acid composition is different from Oleum Cocois, there is certain difference in its alkylolamide performance and Oleum Cocois alkylolamide, needs to make by regulation and control that are composite or molecular structure the Oleum Cocois alkylolamide product that product can substitute or Some substitute is similar.And palm-kernel oil because of lipid acid composition similar to Oleum Cocois, be considered to alternative its be applied in oil and fat chemical field, but at present to being that raw material adopts the synthesis condition of glycerine ester process synthesis alkylolamide and studying in great detail of processing parameter seldom to have bibliographical information with palm-kernel oil.
It is higher that alkylolamide series products adopts the synthesis of glycerine ester process still to there is temperature of reaction, the problem that coloured product is darker.And the product classification, requirement, test method, inspection rule, storage etc. of GB GBT15046-2011 to diethanolamine of fat acyl all specify, wherein top grade product color and luster requires to be less than 300(APHA), salable product require to be less than 500(APHA).For the requirement that touches the mark, improve product quality, strengthen the market competitiveness, product needs the means process through necessity in process of production, just can obtain satisfactory product.According to relevant document patent report, raising product quality conventional at present, the mode reducing product color mainly contains three kinds.(1) raw material is processed, as decoloured to crude oil, depickling, deodorization process (Ge Zan etc., CN102153487A), or directly use purity higher, the good treated oil of quality; (2) reaction conditions is controlled, as under certain vacuum tightness, logical nitrogen protection reaction (Jiangsu Petrochemical Engineering College journal,, or add neutralizing agent in reaction process 1998,10 (3): 54 ~ 56), underpressure distillation (Yang Xiu congruence, CN101774936A); (3) product is processed, as organic solvents available as Virahol, water, acetone, sherwood oil etc. carry out recrystallization (daily chemical industry to product, 2002,32 (02): 26 ~ 29), also by Methods For Purifications (Huang Yaru etc., CN1680283A) such as liquefied petroleum gas (LPG) extraction, acid treatment, with carclazyte or gac to product decolouring (Fu Xiangdong etc., CN201574124U), be also a kind of direct, conventional method.Although for different reaction systems, take above three kinds of modes reducing color and luster to have certain effect, also there is following shortcoming: (1) Feedstock treating makes complex process, production cost increases; (2) control of reaction conditions requires high to production unit and production process; (3) product aftertreatment is restricted, and adds the difficulty of explained hereafter.There are bibliographical information anion surfactant and amides unstable under illumination condition, can degrade (daily chemical industry, 2001,5:32 ~ 36).Therefore alkylolamide series products market sold adopts opaque bucket to pack mostly, and all clearly state product should be placed in room temperature cool place place.This traditional concept continues into the present by the people being engaged in this area, and requires to avoid direct sunlight at the links of products production, storage, transport etc.
Prepare the technology of alkylolamide series products in view of existing and reduce the method for this compounds color and luster, needing to develop a kind of operation steps is few, equipment requirements is low, temperature and pressure milder prepares alkylolamide series products technology and reduce the method for product color.
