7.A special oil-based gelled fracturing fluid,Which combines gellant,crossing-linking agent,surfactant,exciting agent and breaker is presented and tested.
12.A detergent for cleaning iron monosulfide was formulated with surfactant, diamino-propadiene, citric and EDTA, and its cleaning mechanism was discussed.
13.Self-preparation polymerizable macromolecular surfactant HTP and acrylate monomer were used to prepare the amphiphilic polymer by soap-free microemulsion pentamer copolymerization.
14.The amino-acid imidazoline amphoteric surfactant was prepared from dichloroethane and vegetable-oil fatty acid as raw materials by aminolysis, esterffication and hydroxymethylation.
15.This artied discussed on the development status of surfactant industry, symebetic route of raw material, biolysis and environrnent foctor and surfactant usege.
17.From rosin purified abietic acid was prepared by using abietic acid as stared material acylamino surfactant was synthesized by maleric anhydride and diethanolamine.
18.The nonionic surfactant palmitic acid monoethanolamide polyglycoside(PMEAPG),which has not been reported in the literature,was obtained by transglycosidation of PMEA with n-butyl glycoside.
19.We developed a new method to determine critical micella concentration of anionic surfactant by adsorption voltammetry, using neutral red, as a probe.
19.Fortunately, specialized cells within the lungs produce pulmonary surfactant, which decreases the surface tension by breaking the bond between water molecules.
