Abstract

Olefines are condensed with formaldehyde or a polymer thereof in the presence of an aqueous acid-reacting condensation catalyst under 75-2000 atmospheres pressure forming 1 : 3-alkane diols or 1 : 3-alkane-diol-cyclic or -linear formals. The temperatures may be 30 DEG C.-250 DEG C. and preferably 100 DEG C.-200 DEG C. When some of the 1,3-alkane-diol-cyclic formals are added to the feed or when the molar ratio of water to formaldehyde is about 8 : 1, the diols are largely formed, but if the water/formaldehyde ratio is 1 : 1 the formals are mainly formed. The preferred olefines are ethylene, propylene or butylene and the catalysts are, e.g hydrated boron fluoride, sulphuric acid, methyl formate, formic acid, acidic clay-like materials, phosphoric acid or calcium sulphate. The reaction vessel is made or lined with an acid resisting material such as stainless or mild steel, copper, silver, nickel, enamel and glass and the process may be conducted continuously. In examples: (1) a mixture of trioxymethylene, water, sulphuric acid and 1,3-butylene glycol cyclic formal is agitated at 165 DEG C. under 600 to 700 atmospheres of propylene pressure. The product is cooled, neutralized with aqueous calcium oxide, filtered and distilled to yield mainly 1,3-butylene glycol with some butylene glycol cyclic formal and isopropanol; (2) the same reactants as in (1) but with less water and without the addition of cyclic formal are agitated at 150 DEG C. and 200 atmospheres propylene pressure. The product is extracted with chloroform and yields 1,3-butylene glycol cyclic formal. The aqueous layer is neutralized and on distillation yields mainly 1,3-butylene glycol linear formals and a little 1,3-butylene glycol; (3) the same reactants as in (2) but with more water are heated at 190 DEG C. under 900 atmospheres ethylene pressure. Extraction with chloroform yields trimethylene glycol cyclic formal and the aqueous layer yields trimethylene glycol. According to the Provisional Specification any high pressure may be employed. Specifications 511,966 and 544,737 are referred to.
