Description

Hydrolyzate depickling treatment resin during Beta-alanine is prepared using zein
Technical field：
The present invention relates to technical field of biochemical industry, and in particular to one kind prepares Beta-alanine process reclaimed water using zein Solution liquid depickling treatment resin.
Background technology：
Beta-alanine, clear crystal is soluble in water, is slightly soluble in ethanol, insoluble in ether and acetone, there is danger somewhat to water Evil, be mainly used in plating corrosion inhibiter, biochemical reagents, prepare the cold smoked plum of chloramphenicol intermediate calcium pantothenate and other microorganisms The research such as and biochemistry.The preparation method of Beta-alanine mainly includes chemical synthesis and protein Hydrolyze method, and chemistry is closed Into method, although obtained product yield is high, but is more or less directed to use with poisonous and harmful solvent, comparatively protein Hydrolyze method Process safety it is higher, therefore so far still as the important channel for preparing Beta-alanine.
Zein, or alcohol soluble protein, are that the important source material for preparing Beta-alanine is obtained, it is necessary to pass through hydrolysis, acid out.And The acid out of hydrolyzate is relatively strong, it is necessary to carry out depickling treatment.Traditional deacidifying process using add inorganic base neutralize by the way of, such one Can generate a large amount of inorganic salts while depickling, post-processing must remove inorganic salts using the washing of a large amount of water, therefore not only increase Water consumption, while reduce the yield of product Beta-alanine.For this problem, our company develops a kind of hydrolyzate depickling Treatment resin, depickling treatment can be quickly carried out using the resin, and will not generate other accessory substances and increase is post-processed into This.
The content of the invention：
The technical problems to be solved by the invention are that to provide a kind of deacidification efficiency high, and will not generate other accessory substances and The utilization zein for increasing post processing cost prepares hydrolyzate depickling treatment resin during Beta-alanine.
The technical problems to be solved by the invention are realized using following technical scheme：
Hydrolyzate depickling treatment resin during Beta-alanine is prepared using zein, by the raw material of following parts by weight It is made：
Styrene diethylene benzene copoly mer 25-30 parts, acrylonitrile-butadiene-styrene copolymer 4-8 parts, span Imide resin 3-6 parts, PNBR 3-6 parts, chliorinated polyvinyl chloride 2-4 parts, ceramic 2-4 parts, nanometer magnesium silicate Aluminium 2-4 parts, the 1-2 of resistance to acid assistant parts, microwax 1-2 parts, asbestos wool 0.5-1 parts, polyvinyl alcohol resin 0.5-1 parts, C5 hydrogenation stones Oleoresin 0.5-1 parts.
Its preparation method comprises the following steps：
(1) to bimaleimide resin and chliorinated polyvinyl chloride is added in styrene diethylene benzene copoly mer, with 5 DEG C/programming rate of min is warming up to 125-130 DEG C of insulation mixing 30min, adds microwax and polyvinyl alcohol resin, continue In 125-130 DEG C of insulation mixing 10min, room temperature is then naturally cooled to, obtain final product material I；
(2) to PNBR and resistance to acid assistant is added in acrylonitrile-butadiene-styrene copolymer, with 5 DEG C/min Programming rate be warming up to 105-110 DEG C insulation mixing 20min, be subsequently adding nanometer aluminium-magnesium silicate and C5 hydrogenated petroleum resins, Continue to be warming up to 125-130 DEG C of insulation mixing 10min with the programming rate of 5 DEG C/min, then naturally cool to room temperature, obtain final product material II；
(3) to material II, ceramic and asbestos wool is added in material I, it is transferred to after being sufficiently mixed in 120-125 DEG C of environment 15min is stood, is washed 3 times with 65-70 DEG C of hot water after naturally cool to after room temperature, most obtain final product goal tree after suction filtration, drying afterwards Fat.
The resistance to acid assistant is made up of the raw material of following parts by weight：Chlorinated polyethylene rubber 5-10 parts, polytetrafluoroethylene (PTFE) Superfine powder 3-5 parts, PAMA 2-3 parts, 1-2 parts of petroleum coke micro mist, glass fiber powder 1-2 parts, nano zine oxide 0.5-1 parts, sulfurized lard 0.1-0.3 parts, its preparation method is：To adding superfine powder of polytetrafluoroethylene in chlorinated polyethylene rubber With petroleum coke micro mist, microwave treater microwave treatment 5min is utilized after being sufficiently mixed, adds nano zine oxide and sulfurized lard, Continue microwave treatment 5min after well mixed, be then cooled to 70-75 DEG C with the cooling rate of 5 DEG C/min, and add anion Polyacrylamide and glass fiber powder, in room temperature is naturally cooled to after 70-75 DEG C of insulation mixing 5min, gained mixture feeding is super In trickle powder grinder, that is, resistance to acid assistant is obtained.
The rated operation frequency of the microwave treater is 2450MHz, power output is 700W.
The addition of resistance to acid assistant can effectively reduce corrosivity of the acid radical ion to made resin in hydrolyzate.
Using preceding by modification, its processing method is the asbestos wool：Asbestos wool is dispersed in water, is soaked Reflux state insulation mixing 5min is warming up to the programming rate of 5 DEG C/min after 30min, poloxamer and the poly- horse of hydrolysis is added Carry out acid anhydrides, continue the insulation mixing 10min that flows back, 55-60 DEG C of insulation mixing is then cooled to the cooling rate of 5 DEG C/min 10min, and trihydroxymethylpropanyltri diglycidyl ether is added, by gained mixture feeding after 55-60 DEG C of insulation mixing 5min In freeze drier, will finally dry gained solid and be ground into powder.
The quality of the asbestos wool, water, poloxamer, HPMA and trihydroxymethylpropanyltri diglycidyl ether Amount ratio is 10-15:25-35:0.5-1:0.5-1:0.3-0.5.
Asbestos wool effectively improves its comixing compatibility between macromolecular material, and strengthen by above-mentioned modification The deacidification effect of made resin.
The beneficial effects of the invention are as follows：The made resin of the present invention is strongly basic anionic resin, to inorganic acid radical ion Adsorptivity is stronger, can carry out quick depickling treatment to preparing the hydrolyzate during Beta-alanine using zein, and through depickling Other accessory substances will not be generated in hydrolyzate after treatment, it is to avoid use a large amount of inorganic salts of generation existed with mode in inorganic base The problem of washing process is needed, so that processing cost is reduced, beneficial to the preparation of high-volume Beta-alanine.
