| 中文摘要: |
| 利用天然山茶油为主要原料，以聚乙二醇为催化剂，乙醇为增溶剂，与氢氧化钾进行皂化制备天然山茶油皂液。通过单因素实验和正交实验优化天然山茶油皂液的制备工艺条件，并考察了产品的表面张力、临界胶束浓度、发泡性及乳化性。结果表明：制备天然山茶油皂液的最佳工艺条件为反应温度90 ℃、反应时间6 h、碱液（1 mol/L氢氧化钾乙醇溶液）添加量60 mL（10 g山茶油），在最佳工艺条件下皂化率可达到85.24%；产品的临界胶束浓度为0.95 g/L，最低表面张力为2107 mN/m，5 min内泡沫高度由14.54 cm降至13.97 cm，泡沫稳定性为96.08%，乳化分水时间为5.06 min，表明山茶油皂液具有优良表面活化性能。 |

| Natural oil-tea camellia seed oil soap solution was prepared by oil-tea camellia seed oil and potassium hydroxide, with polyethylene glycol as catalyst and ethanol as solvent. The preparation conditions of natural oil-tea camellia seed oil soap solution were optimized by single factor experiment and orthogonal experiment. The physicochemical indexes of the product such as surface tension, critical micelle concentration, foaming properties and emulsifying ability were investigated.The results showed that the optimal conditions for preparing oil-tea camellia seed oil soap solution were obtained as follows: reaction temperature 90 ℃, reaction time 6 h and dosage of alkali (1 mol/L potassium hydroxide solution in ethanol) solution 60 mL(10 g oil-tea camellia seed oil). Under these conditions, the saponification rate reached 8524%.The critical micelle concentration, the minimum surface tension and emulsification water separation time of the product were 0.95 g/L, 21.07 mN/m and 5.06 min respectively. The foam height decreased from 14.54 cm at 0 min to 13.97 cm in 5 min with the foam stability of 96.08%. The results of physicochemical performance indicated that the oil-tea camellia seed oil soap solution had excellent surface activation properties. |
