Application

甲醇已被用作十二烷基硫酸钠-聚丙烯酰胺凝胶电泳（SDS-PAGE）分析从斑点沙鲈（斑带副鲈）幼虫中分离的碱性蛋白酶同种型的溶剂。已用于辣椒、号辣椒果皮提取物中胡萝卜素和叶黄素的高效液相色谱分离和定量测定。

General description

据报道，甲醇在择形沸石的存在下经历热化学转化为碳2-碳10烃。有研究提出了钌原子在钌铂催化剂体系上的氧化反应。
甲醇是一种有机溶剂，可以在氧化铜/氧化锌/铝2氧3催化剂存在下由合成气合成。由于其高氢碳比、低烟灰生成倾向、相对低的重整温度以及在室温下以液态存在，它是燃料电池技术中氢源的理想候选物。在直接甲醇燃料电池（DMFC）中，甲醇与空气一起氧化发电。甲醇通过甲醇制烯烃工艺生成的烯烃（乙烯或丙烯）可以替代石油和天然气生产烃类燃料。
