4-甲基吡啶制备
1.由合成法和煤焦化副产中回收制得。由乙醛与氨反应，主要生成2-甲基吡啶和4-甲基吡啶。将氨预热至450℃，与气化后的乙醛混合，通过预热至430℃的装有硅酸铝催化剂的流化反应塔，于410-430℃反应，生成的气体经分离；冷凝，将得到的反应液投入脱水锅，加2%固碱，于92℃回流脱水2h，静置分层；分馏，收集142-144℃馏分，即得4-甲基吡啶。收率以乙醛计为20%（125-130℃馏分为2-甲基吡啶）。
原料消耗定额：液氨1174kg/t；乙醛3019kg/t。
2.精制方法：合成的产品，几乎不含2-甲基吡啶，容易通过蒸馏精制。从煤焦油中提取的产品含有2-甲基吡啶和2,6-二甲基吡啶。可在其中加入氯化钙溶液和盐酸，将所得加成物晶体用氯化钙溶液洗净后用水蒸气分解，再加食盐水处理以除去可溶成分，然后再用氢氧化钾溶液处理，提取油层，可得纯度99.2%的4-甲基吡啶。也可以将其制成草酸盐精制。例如将100mL 4-甲基吡啶加热到80℃，慢慢加入110g无水草酸和150mL沸腾的乙醇，冷后过滤，用少量乙醇洗涤，然后溶解在少量水中，加入过量的50%KOH蒸馏。馏出物用固体氢氧化钾干燥后再蒸馏。
