Direct, acid catalyzed esterification of acryhc acid is the main route for the manufacture of higher alkyl esters. The most important higher alkyl acrylate is 2-ethyIhexyi acrylate prepared from the available 0x0 alcohol 2-ethyl-1-hexanol (see Alcohols, higher aliphatic). The most common catalysts are sulfuric or toluenesulfonic acid and sulfonic acid functional cation-exchange resins. Solvents are used as entraining agents for the removal of water of reaction. The product is washed with base to remove unreacted acryhc acid and catalyst and then purified by distillation. The esters are obtained in 80—90% yield and in exceUent purity. 

The propylene-based chemicals, n- and isobutanol and 2-ethyl-1-hexanol [104-76-7] (2-EH) dominate the product spectmm. These chemicals represent 71% of the world s total oxo chemical capacity. In much of the developed world, plasticizers (qv), long based on 2-EH, are more often and more frequendy higher molecular weight, less volatile Cg, and C q alcohols such as isononyl alcohol, from dimerized normal butenes isodecanol, from propylene trimer and 2-propyl-1-heptanol, from / -butenes and aldol addition. Because of the competition from the higher molecular weight plasticizer alcohols,... 

In the presence of dilute sodium or potassium hydroxide, //-butyraldehyde undergoes the aldol reaction to form 2-ethyl-3-hydroxyhexanal [496-03-7] which, on continued heating, is converted iato 2-ethyl-2-hexenal [26266-68-2]. Hydrogenation of the latter gives 2-ethyl-1-hexanol/7 (94-7%., aptincipal plastici2er alcohol. 

In excess of a million metric tons of 0x0 products are produced in the United States annually. They are used in the manufacture of plasticizers, solvents, and detergents. The principal 0x0 alcohol product, 2-ethyl-1-hexanol [104-76-7] is made from propylene [115-07-1] and represents about 75% of the 0x0 market. 

Ethyl-1-hexanol, used in the synthesis of di(2-ethylhexyl) phthalate plasticizer, is made commercially from bulanal. Show the likely synthesis route.
