中文名稱:L-丙交酯、(3S,6S)-3,6-二甲基-1,4-二氧雜環(huán)己烷-2,5-二酮、左旋乳酸
英文名稱:(3S,6S)-3,6-Dimethyl-1,4-dioxane-2,5-dione、(3S)-cis-3,6-Dimethyl-1,4-dioxane-2,5-dione、L-Lactide
丙交酯是一種有機(jī)化合物,分子式為C6H8O4。為無色透明片狀或針狀晶體,熔點(diǎn)93-95℃,沸點(diǎn)216℃,分子量144,易溶于氯仿,乙醇,不溶于水。易水解,易聚合,應(yīng)低溫保存。與水共沸時(shí),水解成α-羥基丙酸(乳酸) 。
(3S)-順式-3,6-二甲基-1,4-二惡烷-2,5-二酮可用于合成光學(xué)活性的含三吡啶的聚(L-丙交酯)、多分散乳酸低聚物、雙環(huán)和三環(huán)丙交酯衍生物。 用于合成可生物降解的共聚物。
Lactide is an organic compound with the molecular formula C6H8O4. It is colorless, transparent, flaky or acicular crystal, melting point 93-95 ℃, boiling point 216 ℃, molecular weight 144, easily soluble in chloroform, ethanol and insoluble in water. It is easy to hydrolyze and polymerize and should be stored at low temperature. When it is azeotropic with water, it is hydrolyzed to α- Hydroxypropionic acid (lactic acid).
(3S) - cis-3,6-dimethyl-1,4-dioxane-2,5-dione can be used to synthesize optically active poly (L-lactide) containing tripyridine, polydisperse lactic acid oligomers, bicyclic and tricyclic lactide derivatives. It is used to synthesize biodegradable copolymers.
