Embodiment

[0014] The synthetic technique of the acid thickener of the control reaction time of the present embodiment, comprises the following steps:

[0015] (1) Purify the reaction monomer;

[0016] (2) Weigh a certain mass of AMPS solid and dissolve it in distilled water;

[0017] (3) Add a certain amount of AA and DMDAAC solutions into the AMPS solution, and stir to fully dissolve the three monomers in distilled water;

[0018] (4) After mixing evenly, adjust its pH value;

[0019] (5) Then move the reaction mixture solution into a reaction vessel placed in a constant temperature water bath, pass inert gas to exhaust oxygen and stir for a period of time, then add the initiator solution drop by drop;

[0020] (6) Finally, under the protection of an inert gas, the reaction system is heated to carry out the polymerization reaction, and the reaction time is controlled to be 7 hours to obtain the acid thickener.

[0021] The synthesis process of the acid thickener with controlled reac...

Abstract

The invention discloses a synthetic process for an acid fluid thickening agent by controlling of reaction time. The synthetic process for the acid fluid thickening agent by controlling of the reaction time comprises steps like carrying out monomer purification; dissolving a 2-acrylamido-2-methylpropane sulfonic acid (AMPS) solid in distilled water; adding acrylic acid (AA) and a diallyl dimethyl ammonium chloride (DMDAAC) solution into an obtained 2-acrylamido-2-methylpropane sulfonic acid (AMPS) solution, and carrying out stirring; adjusting a pH value; exhausting oxygen and then adding an initiator; and controlling the reaction time so as to obtain the acid fluid thickening agent. The synthetic process provided by the invention can successfully synthesize the acid fluid thickening agent and has the advantages of high synthesizing efficiency, low synthesizing cost and simple operation; the synthesized acid fluid thickening agent can be directly used without the need for removing a solvent, and is favored by the broad masses of workers in oil fields; meanwhile, through controlling of polymerization reaction time, intrinsic viscosity and conversion rate of the acid fluid thickening agent are improved.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a synthesis process of an acid thickener with reaction time control. Background technique [0002] Thickeners are some solid substances with a thickening effect, which can form a special structural framework in grease. The thickener can disperse and form a structural skeleton in the base oil, and make the base oil be absorbed and fixed in the structural skeleton, thus forming a semi-solid lubricating grease with plasticity. In the current synthesis process method of acid thickener, the technological process is not easy to implement, the resulting acid thickener has low purity, low single-pass conversion rate of reactants, complex production process, low production efficiency and high cost, which is not necessary. Suitable for mass production. Contents of the invention [0003] In order to overcome the above-mentioned technical problems existing in t...
