邻甲酚制备
从煤焦化所得的酚油中切取的甲酚馏分含邻甲酚6%，间甲酚49.4%，对甲酚32.1%，还含二甲酚及少量苯酚。邻甲酚沸点比间、对甲酚低10℃，有可能利用一般蒸馏塔将其分离。将粗酚蒸馏切取的邻甲酚馏分在不低于40块理论塔板的精馏柱内蒸馏，回流比采取14-15：1，切取馏程为188-192℃，获得的精邻甲酚熔点约29℃，纯度大于97%。合成法主要有以下几种：
1. 苯酚烷基化法 以苯酚、甲醇为原料，在约4.14MPa表压下及三氧化二铝催化剂存在下进行甲基化而得。
2. 邻甲苯胺法 该法用于试剂生产，由邻甲苯胺重氮化、水解而得。
3. 甲苯羟基化法
4.将邻甲苯胺加入硫酸溶液中，搅拌冷却后得到邻甲苯胺硫酸盐，加入冰块降温至0～5℃，维持此温度范围，边搅拌边缓慢加入饱和的亚硝酸钠溶液至淀粉-碘化钾试纸不褪色为反应终点。所得重氮盐加入浓硫酸充分搅拌均匀，停止搅拌，待反应物激烈反应后再通入蒸汽加热至完全水解。静置分层，取下层油状物，加入5%氢氧化钠，滤去不溶性杂质，然后用25%的硫酸中和至ph值为。静置分层，取油层，用水洗涤2次，所得粗品采用减压蒸馏，于1333Pa收集74～75.5℃馏分，即得成品。过程反应式为：
