    摘要： Reagents and methods with low thermodynamic barriers can convert lower alkanes such as methane into methanol or other derivatives. One system uses a small quantity of a non-salt radical initiator such as Marshall's acid, a di-acid peroxide that can be split into two radicals. These radicals will remove hydrogens from methane, to generate methyl radicals. Sulfur trioxide is added, and methyl radicals combine with it to form methylsulfonate radicals. Methane is added, and the methylsulfonate radicals will remove hydrogens from it, to form stable methanesulfonic acid (MSA) while creating new methyl radicals to sustain the chain reaction. MSA that is removed can be sold or used, or it can be split into methanol (which can be used on site, or shipped as a liquid) and sulfur dioxide (which can be oxidized to sulfur trioxide and returned to the reactor). This anhydrous system creates no salts and minimal waste. An alternate system uses a bi-functional reagent with electrophilic and nucleophilic domains (such as a bromate-sulfate compound) to create coordinated proton and electron shifts in methane, using symphoric and anchimeric effects to create transitional intermediates with low energy barriers, allowing selective formation of intermediates that can be cracked to release methanol. Either system can improve the selectivity and yield of methanol from methane.

    摘要翻译： 试剂和方法具有低热力学屏障可以转换低级烷烃：如甲烷转化成甲醇或其它衍生物。 一个系统使用了非盐自由基引发剂的少量：如马歇尔酸，二羧酸的过氧化物也可以被分成两个基团。 这些基团会从甲烷去除氢，生成甲基自由基。 三氧化硫被添加，和甲基与它结合，形成methylsulfonates自由基。 甲烷的溶液，并将methylsulfonates自由基会从中除去氢，以形成稳定的甲磺酸（MSA），同时创建新甲基自由基，以维持链式反应。 MSA确实被去除可以出售或使用，或者可以将其拆分成甲醇（这可在现场使用或运输作为液体）和二氧化硫（其可被氧化为三氧化硫，并返回到反应器中）。 这种无水系统创建无盐和最少的废物。 备用系统使用具有亲电和亲核结构域的双功能试剂（搜索作为溴酸盐硫酸盐化合物）在甲烷创建协调的质子和电子转移，使用symphoric和邻位的影响以产生具有低能量壁垒过渡中间体，允许选择性地形成 中间体也可以被破解释放甲醇。 任一系统可提高选择性和甲烷的甲醇产率。
