【摘要】 低酯化度的LM果胶和甲醇在酸催化剂(路易斯酸三氟化硼、无机酸硫酸和盐酸)催化下发生甲酯化反应,在合适的反应条件下,通过反应时间的控制可获得不同甲酯化程度的LM果胶产品.更多还原

【Abstract】 The methylesterification of LM pectin having low esterification degrees with MeOH by the presence of some catalysts （BF₃, H₂SO₄, HCl） was observed. The LM pectin having various methylesterification degrees had been prepared by controlling the reaction time.更多还原
