下游产品:2-甲基丙烯酸
爆炸物危险特性:与空气混合, 受热、明火可爆
蒸气压:64 mm Hg ( 20 °C)
用途一:重要有机合成原料，经水解、酯化可得甲基丙烯酸甲酯，它本身也能聚合成高分子材料。
可燃性危险特性:遇明火、高温、氧化剂易燃; 燃烧产生有毒氮氧化物和氰化物烟雾
毒性分级:剧毒
Acros Organics:甲基丙烯腈（禁运） Methacrylonitrile, stabilized, 99%(126-98-7)
类别:易燃液体
职业标准:TWA 3 毫克/ 立方米; STEL 9 毫克/立方米
刺激数据:眼睛- 兔子 500 毫克/ 24小时轻度; 皮肤- 兔子 200 毫克轻度
MSDS 信息:2-甲基丙烯腈(126-98-7).msds
Sigma Aldrich:126-98-7(sigmaaldrich)
方法一:由混合碳四烃氨氧化制得。原料碳四烃主要含正丁烯-1为44.2%，异丁烯为31.6%，丁烯-2为12.5%，基余为少量其他碳四烃。原料碳四烃、氨和以水饱和的湿空气按配比（1：1.4：13-14）在预热器中混合，并预热到180-200℃，从反应器底部进入反应器，以0.5m/s的线速度使催化剂呈流化状态，在440-460℃进行催化反应，催化剂为磷-钽-铋-锑，异丁烯转化率为77.15%，甲基丙烯腈单程转化率为51.7%。由于碳四烃饱分中含有正丁烯，经氧化为丁二烯，收率为44.9%以上，1-丁烯转化率达76.31%，因此，采用此可得两种产品。
