Abstract

Abstract In this work, hydroxymethyl octadecyltrimethyl ammonium chloride (HM-OTAC) was obtained from the reaction between octadecyltrimethyl ammonium chloride (OTAC) and formaldehyde in different molar ratios. The effects of the reaction conditions (different molar ratios) on the properties of the product (surface tension, foaming, high temperature resistance, methanol resistance and salt resistance) were investigated. The results showed that the HM-OTAC produced under different molar ratios could lower the surface tension of water solutions more than the surfactant OTAC. The HM-OTAC (1:2) reduced the surface tension to 28.29 mN m−1. The HM-OTAC produced under other molar ratios gave higher interfacial tensions than HM-OTAC (1:2). With increasing surfactant concentration, the foam volume first increased and then gradually decreased. At a concentration of 0.3 wt.%, the highest foam volume (460 mL) was produced with HM-OTAC (1:3). Compared to OTAC, the foams produced by each HM-OTAC surfactant exhibited higher temperature stability. In the presence of 30 mL methanol, the initial foam volume of all HM-OTAC surfactants (0.3 wt.%) was generally higher than that of OTAC. With 300 mL HM-OTAC (1:4) solution, the highest foam volume of 20.2 mL could be produced. HM-OTAC (1:3) showed the highest salt resistance.

羟甲基十八烷基三甲基氯化铵的制备及其发泡活性

摘要以十八烷基三甲基氯化铵(OTAC)为原料，在不同的摩尔比下与甲醛反应，得到羟甲基十八烷基三甲基氯化铵(HM-OTAC)。考察了反应条件(不同摩尔比)对产物表面张力、发泡性、耐高温性、耐甲醇性和耐盐性等性能的影响。结果表明，在不同摩尔比下制备的HM-OTAC比表面活性剂OTAC更能降低水溶液的表面张力。HM-OTAC(1:2)使表面张力降至28.29 mN m−1。在其他摩尔比下生成的HM-OTAC比HM-OTAC(1:2)具有更高的界面张力。随着表面活性剂浓度的增加，泡沫体积先增大后逐渐减小。在0.3 wt.%的浓度下，HM-OTAC(1:3)产生的泡沫体积最大(460 mL)。与OTAC相比，HM-OTAC各表面活性剂制备的泡沫具有更高的温度稳定性。在30ml甲醇存在下，所有HM-OTAC表面活性剂的初始泡沫体积(0.3 wt.%)普遍高于OTAC。300 mL HM-OTAC(1:4)溶液可产生20.2 mL的最高泡沫体积。HM-OTAC(1:3)的耐盐性最高。
