摘要
采用气相色谱-质谱联用仪分析了蓖麻油碱裂解料液的化学组成,研究了溶剂种类、用量对碱裂解料中苯酚和NaOH浸出性能的影响.结果表明:甲醇-叔丁醇混合溶剂(体积比为1∶1)对苯酚和NaOH的浸出具有高选择性;当溶剂用量为6mL/g时,苯酚回收率可达80%,NaOH回收率可达72%.
The chemical compositions of the products of castor oil cracking were analyzed by gas chromatography-mass spectrometry and then the effect of solvents and its volume on the leaching performance of phenol and sodium hydroxide in the products of castor oil cracking were studied.The results show that methanol-tert-butanol（V（methanol）∶V（butanol）=1∶1） mixed solvents exhibit high leaching selectivity towards phenol and sodium hydroxide.When the solvent dosage is 6 mL/g,the recovery of phenol and sodium hydroxide can be up to 80% and 72%,respectively.
