4-acctyl-5-methyl-2-

Esters. The significant esters of citric acid arc trimethyl citrate, methyl citrate, tributyl citrate, and acctylaled methyl- and tributyl citrate. Many other esters are available but have nol been used on a commercial scale. Citric acid esters are made under azeotropic conditions with a solvent, a catalyst, and the appropriate alcohol. [Pg.384]

Acetylation of saccharide hydrazones (65) with acetic anhydride in pyridine affords per-O-acetylatcd derivatives (such as 66) with acyclic hydrazones and A-acetyl-O-acetyl derivatives with the cyclic ones. 5 "4 t 4,i63 jn [1C as, casC [lc [sjpi group attached to the aryl moiety is not acetylated, but the more basic NH group attached to the sugar moiety is acetylated. The 0-acetyl groups are split off by base more readily than the iV-acctyl groups.218 and methods for selective saponification have been devised. With acetyl chloride in A/, A-tli methyl aniline, the NH group attached to the aryl residue becomes acylated and acyclic hexose hydrazones give A-acetyl-penta-O-acctyl derivatives (64) 165 similarly, benzoylation with benzoyl chloride in pyridine affords W-benzoyl-0-bcnzoyl deri vatives (Scheme 15)219... [Pg.191]
