【用途七】
甲酸是基本有机化工原料之一，广泛用于农药，皮革，纺织，印染，医药和橡胶工业等，还可制取各种溶剂，增塑剂，橡胶凝固剂，动物饲料添加剂及新工艺合成胰岛素等。我国的甲酸消费中，医药工业约占45%，化学工业约占30%，轻工，纺织等其它部门约占25%。甲酸是我国重要的出口化工产品之一。目前我国甲酸生产全部采用甲酸钠法。甲酸常用作廉价的，挥发性和腐蚀性较小的无机酸的代用品，广泛用于轻工行业。在纺织和印染工业中，甲酸用作消除印地科素亚硝酸钠法所产生的亚硝酸气用剂，弱酸性染料和中性络合染料染色助剂，活性染料染锦纶的助染剂。甲酸不会在印染过程中残留在织物上，酸性较乙酸强，能使六介铬还原，因此可在铬媒染过程中提高染料的利用率。用甲酸代替硫酸可避免纤维素降解，而且酸度适中，染色均习，因此是一种优良助染剂。甲酸作为无机酸的代用品，用于鞣革中的脱色，脱毛，中和石灰和防止湿皮革的发霉。用甲酸作凝固剂可以提出高天然橡胶的质量，降低生产成本，也可用于废旧橡胶的再生。用甲酸制作饲料添加剂，在青贮饲料方面有很大潜力。甲酸有抑制或防止霉菌生长的功能，对饲料能改变天然的发酵形式，常添加脂酸以增进抗霉效果。用甲酸处理过的青饲料喂奶牛能防止冬季牛奶减产，育肥效果也有明显提高。在食品工业中，甲酸用于酿酒行业的消毒，防腐，用作罐头的清洗消毒剂，果汁和食物的保藏剂。甲酸的大量衍生物是医药，农药，染料，香料，溶剂的中间体，用于制造冰片，氨基比林，咖啡因，维生素B1，安乃近，杀虫脒，粉锈宁，三环唑，二甲基甲酰胺等。甲酸衍生物中以取代的甲酰胺和甲酸酯类在工业上应用较多（甲酰胺的衍生物见该品条目）。甲酸的酯类在香料工业中用途很广，如：甲酸乙酯——桃，莓等果实香精；甲酸异戊酯——果实香精，皮革用香精；甲酸已酯——苹果香精；甲酸庚酯——杏，梅，桃等果实香精；甲酸正癸酯——橙花香精及鸢尾油用；甲酸苄酯——素馨等花香及皂用香精；甲酸桂酯——素馨及月下香等香精用；甲酸香茅酯——用于玫瑰，桂花，野百合等香精；甲酸丁香酯——用于康乃馨香精等；甲酸香叶酯——玫瑰，橙花，香叶等香精；甲酸芳樟酯——薰衣草，香柠檬等香精；甲酸薄荷酯——化妆品香精，喷雾用香精；甲酸苯乙酯——白玫瑰，兰花，菊花等香精；甲酸百里香酯——化妆品香料。
【用途八】
还原剂，测定砷、铋、铝、铜、金、铟、铁、铅、锰、汞、钼、银和锌等，检定铈，铼和钨，检验芳香族伯胺和仲胺，测定分子量及结晶的溶剂，测定甲氧基，显微分析中用作固定剂，制造甲酸盐类。

详细合成路线

甲酸上游产品

甲酸下游产品

1.甲酸钠法　一氧化碳和氢氧化钠溶液在160-200℃和2MPa压力下反应生成甲酸钠，然后经硫酸酸解、蒸馏即得成品。

2.甲醇羰基合成法（又称甲酸甲酯法）　甲醇和一氧化碳在催化剂甲醇钠存在下反应，生成甲酸甲酯，然后再经水解生成甲酸和甲醇。甲醇可循环送入甲酸甲酯反应器，甲酸再经精馏即可得到不同规格的产品。

3.甲酰胺法　一氧化碳和氨在甲醇溶液中反应生成甲酰胺，再在硫酸存在下水解得甲酸，同时副产硫酸铵。原料消耗定额：甲醇31kg/t、一氧化碳702kg/t、氨314kg/t、硫酸1010kg/t。另外，丁烷枵轻油氧化法主要用来生产乙酸，甲酸作为副产品回收，处于研究阶段的方法有一氧化碳和水直接合成法。

精制方法：无水甲酸可在减压下直接分馏制得，分馏时用冰水冷却凝结。对含水甲酸，可用硼酐或无水硫酸铜做干燥剂。五氧化二磷和氯化钙能与甲酸作用，不宜用作干燥剂。对试剂级88%的甲酸，可用邻苯二甲酸酐回流6小时后蒸馏的方法除去其中的水分。进一步纯化可利用分步结晶法。甲酸与乙酸混在一起时，可加入脂肪烃进行共沸蒸馏分离。

4.将适量的一氧化碳和氢氧化钠水溶液在160～200℃下反应生成甲酸钠，经中和、蒸馏、冷凝而得。或者在三乙胺水溶液中，以钯络合物为催化剂，二氧化碳与氢气于140～160℃反应制得。

5.以甲酸钠与浓硫酸作用制得工业级甲酸，然后可用活性炭吸附后减压蒸馏以制得纯品，也可加入B₂O₃ CuSO₄进行减压蒸馏精制。

6.二氧化碳法　在钯络合物催化下，在三乙胺水溶液中，二氧化碳与氢气于140～160℃反应而得。反应式：

7.主要采用合成酸化法和高压催化法。合成酸化法：用焦炭燃烧产生的一氧化碳与氢氧化钠合成甲酸钠，再用硫酸酸化，经蒸馏而得。高压催化法：将一氧化碳和水蒸气在催化剂存在下，于高温高压下反应而得。

8.制法：将甲酸与五氧化二磷混合，进行减压蒸馏，反复5一10次，方可得到无水甲酸,但得量低，费时长，会造成一些分解。将甲酸与硼酸醉进行蒸馏，操作简便，效果更好。将硼酸置甩沪中高温脱水至不再产生气泡，所得熔融物倒在铁片一上，置干燥器中冷却，然后研磨成粉。将硼酸酚细粉加到甲酸中，放置几日，形成硬块，分出清彻液体进行减压蒸馏，收集22一25℃/12-18mm馏份为产品。蒸馏器应是全磨口接头并有干燥管保护。
