1-O-Alkyl (di)glycerol ethers synthesis from methyl esters and triglycerides by two pathways: catalytic reductive alkylation and transesterification/reduction
esters, monoglycerides or oleic sunflower refined oil, the corresponding 1-O-alkyl (di)glycerolethers were obtained in both high yields and selectivity by two different pathways. With methyl esters, a reductivealkylation with (di)glycerol was realized under 50 bar hydrogen pressure in the presence of 1 mol% of Pd/C and an acid co-catalyst. A second two step procedure was evaluated from methyl esters
从可用的和生物来源的甲酯中, 甘油单酸酯或油酸向日葵精制油,通过两种不同途径以高收率和选择性获得了相应的1- O-烷基(二)甘油醚。对于甲酯,在1mol%的Pd / C和酸助催化剂的存在下,在50巴的氢气压力下,实现了与(二)甘油的还原性烷基化。从甲酯或三油精 包括第一次酯交换反应成相应的 甘油单酸酯与BaO / Al 2 O 3 催化剂,然后 减少在H 2压力下,用可循环利用的非均相催化体系Pd / C和Amberlyst 35合成所需的甘油单醚。另外,还提出了反应机理。
