摘要

摘要: 从催化剂用量、酯交换温度及时间、醇油物质的量比等影响因素出发,并借助热重、X射线荧光光谱、X射线衍射、氮气吸附与哈米特指示剂等催化剂表征手段,研究造纸白泥催化花生油与甲醇的酯交换特性.造纸白泥通过800 ℃煅烧-常温水合-600 ℃活化处理后,成分以CaO为主、比表面积为7.28 m²/g、碱性强度为9.8<H_<15.0;花生油成分以二元不饱和亚油酸为主,酸值为0.44 mgKOH/g;较优的酯交换工况为催化剂质量分数6%、酯交换温度64 ℃、酯交换时间2 h以及醇油物质的量比12,相应甘油收率为90.74%;造纸白泥具有较好的重复使用性能,较优工况下,分离、回收第六次使用时,仍能取得88.63%的甘油收率.

Abstract: The catalytic performance of papermaking white clay in the transesterification of peanut oil with methanol was investigated in terms of catalyst quantity, molar ratio of methanol to oil, reaction temperature, and time. Meanwhile, the catalyst is characterized by thermogravimetric analysis, X-ray fluorescence, X-ray diffraction, nitrogen adsorption and Hammett indicator. After a sequence of pretreatments involving calcination at 800 ℃, hydration at room temperature and activation at 600 ℃, the catalyst mainly consists of calcium oxide, with surface area of 7.28 m²/g and basic strength of 9.8 < H_ < 15.0. The preferred conditions are catalyst percentage of 6%, methanol/oil molar ratio of 12 and reaction time of 2 h at 64 ℃; under these conditions, the transesterification efficiency reaches 90.74%. The catalyst from papermaking white clay exhibits good reusability; after being reused for six times, the transesterification efficiency remains above 88.63% under the preferred condition.
