Abstract
The present invention discloses a production process of quaternary ammonium salt cationic polymer HMAT, which is characterized in that: a method of the present invention for the synthesis of quaternary ammonium salt takes a monomer I, a monomer II and a compound III as the raw materials, the operation process of the process is that: a reactor is pumped into the negative pressure and uses N2 to convert the air in the reactor, the deionized water is added, the measurable monomer II is added in the reactor by a closed pipeline, the monomer I is added slowly by stirring under the condition of 25 DEG C, then the temperature of the reactor is increased to 200 DEG C for reaction for 2 to 3 hours, the compound III is added slowly, the reaction temperature is controlled at about 100 DEG C, the temperature is kept for 1 to 2 hours, the temperature is decreased to 40 to 50 DEG C after the completion of the reaction, and then the product is obtained by material discharging and dehydration under the negative pressure. The present invention can improve the conversion rate of main products, increase the yield of the main products and improve the quality of the product. The prepared product has high temperature resistance, good anti-swelling effect, and long validity period and so on.
Description
Technical field:
The present invention relates to a kind of production technique of quaternary ammonium salt cationic polymer HMAT, belong to the organic chemical industry field.
Background technology
High temperature resistant quaternary ammonium salt cationic polymer HMAT in the market is colourless to light yellow thick liquid, relative density is under the 0.95-1.05 (4-25 ℃), viscosity 30-90mPa.s, soluble in water, be dissolved in ethanol, ethyl acetate etc., be insoluble to mineral oil, stable under the room temperature, steel, aluminium etc. there are not corrosion, be mainly used in expansion-resisting agent in the oil field.The anti-swollen measure in stratum is the necessary means of oil layer protection, and temperature is higher during owing to thermal production well filling vapor, and general organic expansion-resisting agent is non-refractory all, though the high temperature resistant validity period of inorganic expansion-resisting agent is short, and anti-swollen weak effect.
Summary of the invention
The objective of the invention is problem, propose a kind of production technique that can resistant to elevated temperatures organic expansion-resisting agent at above-mentioned appearance.
Solve already present technical problem in order to reach, concrete technical scheme of the present invention is: the production technique of quaternary ammonium salt cationic polymer HMAT, it is characterized in that: the method for the synthetic quaternary amine of the present invention is a raw material with monomer I, monomer II and compound III, wherein:
Monomer I is the organic amine that contains following general formula:
R1, R2, R3 independently are selected from a kind of in C1～C10 straight chained alkyl or cyclohexyl, the phenyl respectively;
Monomer II is the organic acid that contains following general formula
R is selected from straight chain alkane or the branched-chain alkyl of H or C1-C10
Compound III is an epoxide
Rn is selected from H, methyl or ethyl
The operating process of this technology is as follows:
Reactor is taken out negative pressure and with air in the N2 conversion still, is added deionized water, adds the monomer II of metering in reactor with closed conduit, under 25 ℃ condition, stir, and slowly add monomer I, reactor is warming up to 200 ℃ then, reacted 2-3 hour, slowly add compound III, and control reaction temperature is incubated 1-2 hour about 100, makes its complete reaction, be cooled to 40-50 ℃, dewater under the discharging, negative pressure, obtain product.
Compared with prior art, advantage of the present invention is:
Can improve the transformation efficiency of major product, increase going out rate and improving the quality of products of major product.The product of institute's output is high temperature resistant, and is anti-swollen effective, and validity period is long etc.
Embodiment:
The production technique of quaternary ammonium salt cationic polymer HMAT, its operating process is as follows:
Reactor is taken out negative pressure and with air in the N2 conversion still, is added deionized water, adds 250 kilograms in the formic acid that measures with closed conduit in reactor, under 25 ℃ condition, stir, and slowly add 360 kilograms of Trimethylamine 99s, reactor is warming up to 200 ℃ then, reacted 2-3 hour, slowly add propylene oxide, and control reaction temperature is incubated 1-2 hour about 100 ℃, makes its complete reaction, be cooled to 40-50 ℃, dewater under the discharging, negative pressure, obtain product.
