The use of carbon dioxide in chemical synthesis is also of great importance in combating the greenhouse effect (the amount of carbon dioxide in greenhouse gases is more than 50%).<\/p>\n The carbon dioxide molecule has a low reactivity, so most of the reactions occurring in it occur only under certain conditions: the use of catalysts and harsh process conditions. In addition, some readily available simple carbon dioxide derivatives are highly active compounds. In particular, syntheses based on alkaline salts of alkyl carboxylic acids are of interest. The latter are easily synthesized by the reaction of carbon dioxide with alcoholates of alkali metals.<\/p>\n Pro\udb40\udc01ducts of phe\udb40\udc01nols car\udb40\udc01boxylation \u2013 hyd\udb40\udc01roxybenzoic aci\udb40\udc01ds and its der\udb40\udc01ivatives, hav\udb40\udc01e wid\udb40\udc01e usi\udb40\udc01ng as sem\udb40\udc01iproducts for obt\udb40\udc01aining pes\udb40\udc01ticides, dru\udb40\udc01gs, pho\udb40\udc01tostabizers, dye\udb40\udc01s and pol\udb40\udc01ymeric mat\udb40\udc01erials.
