2,2-二羟甲基丁酸的制备工艺
Preparation of 2,2-dimethylolbutyric acid
【摘要】 甲醛和丁醛在碱性催化剂的存在下 ,进行羟醛缩合反应 ,制备 2 ,2 二羟甲基丁醛。以过氧化氢为氧化剂 ,通过氧化、结晶 ,得到 2 ,2 二羟甲基丁酸晶体。用红外光谱 (IR)和核磁共振 (NMR)证明了该化合物的结构。研究了反应条件 (例如原料摩尔比、反应温度、分散剂及反应时间 )对反应产率的影响。
【Abstract】 Using inorganic base as a catalyst, 2,2-dimethylolbutyraldehyde was prepared by the aldol condensation from formaldehyde and butyraldehyde. Then, taking hydrogen peroxide as an oxidant, 2,2-dimethylolbutyric acid was obtained. The reaction conditions including molar ratio, reaction time, solvent and reaction temperature were investigated. The structure of the product was confirmed by IR and NMR.
