Preparation Of Triacrylonitrile Silicate Surfactant Modified By Butylene Glycol Ether

In this paper, Chlorine alcohol ether(BAE) was synthesized with Butyne glycol ethers(BEO)and epichlorohydrin with tin tetrachloride as a catalyst. And then BAE reacts with triethylamine in alcohol under reflux conditions to form quatemary ammonium salt allyl alcohol ether(QASBAE).Quatemary ammonium salt cationic trisiloxane surfactant(Gemini-QASBTSS)was synthesized through the hydrosilylation of 1,1,1,3,5,5,5-heptamethyltrisiloxane(MDHM) and QASBAE with platinic chloride as a catalyst. The chemical structure of Gemini-QASBTSS was characterized by IR and proton nuclear magnetic resonance(1HNMR). The interfacial properties of Gemini-QASBTSS were measured, the performance of surface water of wetting and spreading resistance to hydrolysis were compared, Experimental results was showed as follows:1. By synthesizing process optimuing, the most favorable reaction conditions of Chlorine alcohol ether(BAE) which experimental results was showed as follows: the reaction time was2.5h,the mole ratio of Butyne glycol ethers(BEO) and epichlorohydrin was 1:2.5, The best reaction temperature was 50℃, the catalyst dosage of tin tetrachloride was 0.45wt%, Product was obtained as a light yellow color and transparent liquid, The chemical structure of Chlorine alcohol ether(BAE) was characterized by IR.2. As a solvent of the ethanol was heated under the reflux conditions, the quatemary ammonium salt allyl alcohol ether(QASBAE) was synthesized with Chlorine alcohol ether(BAE)and triethylamine which was studied by discussing the reaction time with the mole ratio of Chlorine alcohol ether(BAE) to triethylamine was 1:2.05. the most favorable reaction conditions was that the time was 18 h. The chemical structure of quatemary ammonium salt allyl alcohol ether(QASBAE) was characterized by IR.3. As a solvent of the isopropanol, Quatemary ammonium salt cationic trisiloxane surfactant was synthesized through the hydrosilylation of 1,1,1,3,5,5,5-heptamethyltrisiloxane(MDHM) and QASBAE with platinic chloride as a catalyst. the most favorable reaction conditions of Gemini-QASBTSS which was discussed with the affecting reactions. Experimental results was showed as follows: the reaction time was 6h, the catalyst dosage of platinic chloride was 15 ppm,The best reaction temperature was 105℃, the mole ratio of MDHM and QASBAE ether was1.25:1. The chemical structure of Gemini-QASBTSS was characterized by IR and proton nuclearmagnetic resonance(1HNMR).4. The surface tension of cationic Gemini-QASBTSS surfactant was detected with the maximum bubble method in its aqueous solution. Experimental results was showed as follows:CMC was 6.56×10-4mol·L-1, The surface tension of cationic Gemini-QASBTSS surfactant could be reduced to 22.4m N·m-1.The completely adsorption, single cationic Gemini-QASBTSS surfactant which the average area of the saturated adsorption layer occupies the interface and which reached the standards was required for the free energy of the micellization, which was3.8×10-6mol·m-2, 0.44 nm2 and-28.1 k J·mol-1.5. The wettability and spreadability of cationic Gemini-QASBTSS surfactant were detected with capillary effect and the measurement of balance spreading coefficient which was depended on molecular structure, the surface tension, the clarity of the solution and the average area. The wettability and spreadability of cationic Gemini-QASBTSS was better than cationic QASBAE surfactant.6. At the 25℃, cationic Gemini-QASBTSS surfactant and QASBAE surfactant were detected with volume concussion method in analysis of liquid and foam half-life performance under a range of concentrations. As follows: the analysis of liquid and foam half-life performance of cationic Gemini-QASBTSS was better than cationic QASBAE surfactant.7. The hydrolytic resistance of cationic Gemini-QASBTSS surfactant was compared to cationic QASBAE surfactant in a series of p H value. As follows: The hydrolytic resistance of cationic Gemini-QASBTSS surfactant was better than cationic QASBAE surfactant.
