摘要:
Processes for the purification of bio-based acrylic acid to crude and glacial acrylic acid are provided. The bio-based acrylic acid is produced from hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof. The purification includes some or all of the following processes: extraction, drying, distillation, and melt crystallization. The produced glacial or crude acrylic acid contains hydroxypropionic, hydroxypropionic acid derivatives, or mixtures thereof as an impurity.
摘要(中):
提供了将生物基丙烯酸纯化成粗制和冰丙烯酸的方法。 生物基丙烯酸由羟基丙酸,羟基丙酸衍生物或其混合物制备。 纯化包括一些或全部以下方法:萃取,干燥,蒸馏和熔融结晶。 产生的冰或粗丙烯酸含有羟基丙酸,羟基丙酸衍生物或其作为杂质的混合物。
