Abstract
1428277 α,#-Unsaturated acids and esters MONSANTO CO 2 Aug 1973 [3 Aug 1972 (2)] 36707/73 Heading C2C α,#-Unsaturated acids and esters are obtained by condensing at 400 to 600 C. a compound of Formula I: R-CH 2 -COOR<SP>1</SP>, wherein R is hydrogen or an alkyl, aryl or alicyclic radical and R<SP>1</SP> is hydrogen or an alkyl radical, with formaldehyde in the vapour phase and in the presence of water and a catalyst comprising an alkali metal compound dispersed on a solid carrier, the alkaline supported catalyst having a specific surface area of 350 to 1000 m.<SP>2</SP>/g. (B.E.T.), the feed mole ratio of H 2 O to formaldehyde being from 0À01 : 1 to 10 : 1 and, where R<SP>1</SP> represents alkyl, the feed mole ratio reactant ester : formaldehyde being from 0À1 : 1 to 7À5 : 1 and the alkyl, aryl and alicyclic radicals containing a sufficiently low number of carbon atoms that the products are readily vaporizable without substantial decomposition. The condensation may be effected in the presence of an alkanol R<SP>1</SP>OH (e.g. 1-8 C atoms), the product in the case of an acid starting material then comprising the corresponding unsaturated ester. The formaldehyde may be added as anhydrous paraformaldehyde, trioxane, or as an aqueous or alcoholic solution. Preferred mole ratios of acid starting material I to formaldehyde are 0À1 : 1 to 7À5 : 1, of alkanol to formaldehyde of 0À1 : 1 to 20 : 1 and, in the case of an acid starting material I, of alkanol to acid of 1 : 1 to 5 : 1. The preferred catalyst is KOH dispersed on silica gel. Other specified catalysts are LiOH, NaOH, RbOH, CsOH and alkali metal carbonates and other specified carriers are SiO 2 , Al 2 O 3 and SiO 2 /Al 2 O 3 . Examples prepare acrylic acid and its methyl, ethyl and 2-ethylhexyl esters, methacrylic acid and its methyl ester, α-propyl acrylic acid and its isopropyl ester. Other specified starting materials are butyric acid and its methyl ester, phenylacetic acid and its methyl ester, 2-ethylhexyl acetate and nbutyl and ethyl propionate.
