With CD-ROM., Hardcover RefComment: Written for: Scientists and researchers in the fields of physics, chemistry, materials science RefComment: Supplement and Revised Editon to II/16 Abstract: The volume II/27 has been divided into three subvolumes according to the classes of compounds: Subvolume A: Diamagnetic susceptibility and magnetic anisotropy of inorganic and organometallic compounds; Subvolume B: Diamagnetic susceptibility of organic compounds, oils, paraffins and polyethylenes; Subvolume C: Diamagnetic susceptibility and magnetic anisotropy of organic compounds. The data presented in this volume are based on the literature survey of the chemical abstracts up to 2005. The calculated values of diamagnetic susceptibility of organic compounds in the present subvolume II/27B are presented along with their experimental values. They have been calculated with the use of structural parameters in structural formula by using different theoretical methods available in the literature.

  • 方法一:α-甲基乙酰乙酸乙酯是由乙酰乙酸乙酯与硫酸二甲酯反应制得。 在搪玻璃反应釜中预先加入二甲苯、乙酰乙酸乙酯、硫酸二甲酯和相转移催化剂,搅拌,缓缓加入氢氧化钠溶液,控制反应温度不超过40℃,加毕继续搅拌1.5h,控制pH=8~9,然后静止1h,分出水层,再加水洗至水溶液呈中性,静置,分出水层(送三废处理),二甲苯溶液在减压下脱水,浓缩至含乳甲基乙酰乙酸乙酯含量为35%~40%即可停止浓缩,得乳甲基乙酰乙酸乙酯二甲苯溶液,再脱溶即得产品。 α-甲基乙酰乙酸乙酯还可由乙酰乙酸乙酯、碳酸钾与碘甲烷在一定条件下以固液相烃化反应制得。
