二氧化碳作为工业应用的化学碳源仅限于制造某些羧酸、碳酸酯、尿素以及在甲烷蒸汽裂化过程中用来调整CO/H_2的比例。然而,据报道,大多数实验室有机合成仍然是以二氧化碳作为碳源。因为羧酸的合成是按化学计算的,因此,它的利用要产生副产物钠盐(硫酸盐)。于是,除了传统的化学计算的羧化作用外,二氧化碳用于制备甲烷、甲醇,同系列的链烷烃、链 Carbon dioxide as a chemical carbon source for industrial applications is limited to the manufacture of certain carboxylic acids, carbonates, and urea, and to adjust the CO / H 2 ratio during methane steam cracking. However, it is reported that most of the laboratory organic synthesis still uses carbon dioxide as a carbon source. Because carboxylic acid synthesis is stoichiometric, its use is to generate by-product sodium salts (sulfates). Thus, in addition to the traditional stoichiometric carboxylation, carbon dioxide is used to make methane, methanol, the same series of paraffins, chains
