Abstract

The present invention belongs to the technical field of research on moisture evaporation inhibitor preparation processes, and more particularly relates to a novel heterogeneous moisture evaporation inhibitor preparation method. The inhibitor comprises 0.8-1.4% of even carbon fatty alcohol or 0.6-1% of odd carbon fatty alcohol, 4-10% of short-chain alcohol, 40-65% of petroleum ether, 0.7-1.1% of a fatty alcohol polyoxyethylene ether series emulsifier AEO-3 and / or AEO-5 and / or AEO-7, and the balance of distilled water. The preparation method comprises: (1) according to the ratio, weighing even carbon fatty alcohol or odd carbon fatty alcohol and short-chain alcohol, completely dissolving in petroleum ether at a room temperature, adding a fatty alcohol polyoxyethylene ether series emulsifier, and completely and uniformly mixing so as to be used as a moisture evaporation inhibitor oil phase system; and (2) weighing distilled water, adding to the obtained oil phase system, placing the oil phase system into an ultrasonic wave treatment apparatus, and carrying out intermittent shaking so as to prepare the stable water-in-oil type heterogeneous moisture evaporation inhibitor. The moisture evaporation inhibitor of the present invention has the significant technical effect in the water resource protection field.

Description

technical field

[0001] The invention belongs to the technical field of research on the preparation process of water evaporation inhibitors, and in particular relates to a preparation method of a novel heterogeneous water evaporation inhibitor. Background technique

[0002] As early as the 1950s, American colloid chemists Archer and La Mer conducted a series of experiments on monomolecular membranes to inhibit water evaporation, and initially studied the evaporation of water molecules through lipid, acid, and alcohol monomolecular membranes. rate, and the relationship between its molecular structure and the rate of inhibition of evaporation was studied.

[0003] At present, domestic and foreign theoretical research on liquid film inhibition of water evaporation is mainly based on the use of straight-chain fatty alcohols and straight-chain fatty acids, based on the theory that they can spread on the gas-liquid two-phase interface to form a monomolecular film. Evaporation spec...
