  Disclosed is a method for producing 1-palmitoyl-2-linoleoyl-3-acetyl glycerol of high purity with high yield by carrying out acetylation of 1-palmitoyl glycerol with acetic anhydride or a mixture of acetic anhydride and acetyl chloride. The method for producing 1-palmitoyl-2-linoleoyl-3-acetyl glycerol comprises the steps of: preparing 1-palmitoyl-3-acetyl glycerol intermediate of Chemical formula 2 in the specification by reacting 1-palmitoyl glycerol of Chemical formula 1 in the specification and an acetylating agent selected from the group consisting of (i) acetic anhydride and (ii) a mixture of acetic anhydride and acetyl chloride; and reacting the 1-palmitoyl-3-acetyl glycerol intermediate and linoleic acid.

  本方法披露了一种高纯度、高产率生产1-棕榈酰-2-亚油酰-3-乙酰甘油的方法，通过使用乙酸酐或乙酰氯或乙酸酐和乙酰氯混合物对1-棕榈酰甘油进行乙酰化。生产1-棕榈酰-2-亚油酰-3-乙酰甘油的方法包括以下步骤：通过将规范中的化学式1的1-棕榈酰甘油与来自以下组的乙酰化剂（i）乙酸酐和（ii）乙酸酐和乙酰氯混合物中选择的一种反应，制备规范中的化学式2的1-棕榈酰-3-乙酰甘油中间体；然后将1-棕榈酰-3-乙酰甘油中间体与亚油酸反应。

  Disclosed are a method for preparing 1-acyl-3-acetylglycerol in high purity and high yield without a purification process using a column chromatography, and a method for preparing 1,2-diacyl-3-acetylglycerol in high purity and high yield using the same as a key intermediate. The method includes the steps of: forming a reaction mixture including 1-acyl-3-acetyl glycerol of the Formula 1 in the specification by reacting 1-acylglycerol of the Formula 2 in the specification and an acetylating agent; and separating the racemic or optically active 1-acyl-3-acetylglycerol by crystallizing the reaction mixture in a saturated hydrocarbon solvent having 5 to 7 carbon atoms.

  揭示了一种在高纯度和高产率下制备1-酰基-3-乙酰甘油的方法，无需使用柱层析纯化过程，并且使用相同的方法作为关键中间体制备高纯度和高产率的1,2-二酰基-3-乙酰甘油的方法。该方法包括以下步骤：通过将规范中的1-酰基-3-乙酰甘油的化学式1与规范中的1-酰基甘油的化学式2和乙酰化剂反应形成反应混合物；通过在具有5到7个碳原子的饱和碳氢化合物溶剂中结晶化反应混合物来分离消旋或光学活性的1-酰基-3-乙酰甘油。
