Editor: Gupta, Radha Raman Source: Landolt-Börnstein, New Series Volume: II/27B Year: 2008 Keyword: diamagnetic susceptibility; organic compounds ISBN: 978-3-540-44359-9 (print) ISBN: 978-3-540-45860-9 (online) Internet Resource: doi:10.1007/978-3-540-45860-9 RefComment: VIII, 503 p. 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.

• 上游原料:氢氧化钠 --> 盐酸 --> 硫酸 --> 氰化钠 --> 苄基氯 --> 二甲胺 --> 氰化苄 --> 硫酸氢铵 --> 氢胺
• 用途二:用于香料、制药工业，也用作植物生长激素
• 用途三:GB 2760--1996规定为允许使用的食用香料。主要用以配制奶油、巧克力、桃、草莓、香荚兰豆、蜂蜜和啤酒等型香精，亦为烟用(尤其是哈瓦那雪茄烟)香精。
• 方法一:由氰化苄与稀硫酸作用下水解而得。
• 方法二:其制备方法是将苯乙腈进行酸式水解，即将70％硫酸投入反应釜中，在搅拌下滴加苯乙腈，在130℃反应2h，并加水稀释，分层，分出硫酸氢铵溶液，在120～130℃脱水即得产品。 苯乙酸也可用苯乙腈进行碱式水解，即用苛性钠溶液在115℃时加入苯乙腈，在125～133℃反应3h，再在120～124℃回流3h，然后冷却，加水稀释，用盐酸中和至pH=6.5～7，有絮状物析出，加活性炭脱色，滤液再调pH=2～3，冷至5℃，有结晶析出，过滤干燥得产品。

• 方法三:由苯乙腈水解而得。将52.6kg70%的硫酸加入反应锅，搅拌加热至100℃左右，缓缓滴加苯乙腈，在1h内滴完40kg后升温至130℃，继续保温反应2h。然后加入8kg水，稀释反应生成的硫酸氢胺，静置分层，分去硫酸氢铵母液，在120-130℃减压脱水1h，得纯度96-97%的苯乙酸，收率95-97%。苯乙腈的水解反应也可以在氢氧化钠溶液中进行，在100-104℃回流6h，至油状液体减少为止，冷至5℃，加盐酸调节pH至1-2，甩滤，滤饼用水洗涤，在40℃干燥，得苯乙酸。国内90%以上厂家采用苯乙腈水解法生产苯乙酸。武汉大学化工厂采用羰基合成工艺，用氯苄羰化法制苯乙酸，基本无污染，成本低，节约能源。原料消耗定额：甲苯2200kg/t、液氯（99%）1500kg/t、氰化钠800kg/t、硫酸（98%）1500kg/t、液碱（30%）2500kg/t。
