    • A catalytic process is taught for non-oxidative alkylation of organic compounds, comprising alcohols, alkanes, glycols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, thiols or phosphines, by alkyl groups produced from alcohols or glycols, forming products comprising ethers and other higher molecular weight alkylated compounds. The process is conducted at a reflux temperature below 200° C. in the presence of an acid, alkali or neutral salt dehydrating agent comprising sulfuric acid, phosphoric acid or their salts, lime or anhydrous calcium sulfate in the absence of zero valent metals and air. Specifically, this catalytic process converts ethanol to ethyl butyl ethers, ethyl hexyl ethers and dibutyl ethers or oxygenated gasoline as well as amines comprising n-butyl amine plus butanol to dibutyl amine and butyl hexyl amines at ambient pressure. This same catalytic alkylation chemistry, which does not constitute a condensation reaction, alkylates 4-hydroxybenzoic acid using ethanol to 4-ethoxyethylbenzoic acid products.
    • 教导了通过由醇或二醇生产的烷基对有机化合物(包括醇,烷烃,二醇,醚,醛,酮,羧酸,酯,胺,硫醇或膦)进行非氧化烷基化的催化方法, 醚和其他较高分子量的烷基化化合物。 在不存在零价金属和空气的情况下,在含有硫酸,磷酸或其盐,石灰或无水硫酸钙的酸,碱或中性盐脱水剂的存在下,在低于200℃的回流温度下进行该方法 。 具体地说,该催化方法在环境压力下将乙醇转化为乙基丁基醚,乙基己基醚和二丁基醚或含氧汽油以及包含正丁胺加丁醇的胺至二丁基胺和丁基己基胺。 这种不构成缩合反应的催化烷基化化学反应使用乙醇将4-羟基苯甲酸烷基化成4-乙氧基乙基苯甲酸产物。
