Abstract

1332353 Isoprene SUMITOMO CHEMICAL CO Ltd 25 Sept 1970 [9 Oct 1969 20 Jan 1970 (2) 6 Feb 1970] 45816/70 Heading C5E Isoprene is prepared by reacting isobutene with formaldehyde, dimethyl m - dioxane or isoprene glycol or an acid ester thereof in an aqueous medium at 110-180‹ C. and in presence of a catalyst, such as a metal sulphate, chloride or phosphate. The aqueous medium preferably contains t-butanol (which is in equilibrium with the isobutene) and 1,4-dioxane or toluene as solvents. Surfactants such as choline chloride or polyethylene glycol octylphenyl ether may also be present.
