Patent GB-486015-A (GB)
Title: Manufacture of cyclic acetals of formaldehyde
IPC: C07D317/12
Filed: 1936-11-27
Abstract: Cyclic acetals are produced by reacting aqueous formaldehyde with an organic oxide in the presence of an acid catalyst. Suitable organic oxides are ethylene, propylene and benzyl-ethylene oxides and epichlorhydrin.  The catalyst may be sulphuric, oxalic, or an organic sulphonic acid or a hydrohalogen acid and/or an acid salt such as sodium or potassium bisulphate or a normal salt having an acid reaction such as calcium, aluminium, or zinc chloride.  The reaction may be effected in two stages, the first at 50-100 DEG  C. in the presence of one of the above catalysts which does not contain halogen, and the second at 100-150 DEG  C. in the presence of hydrochloric, or hydrobromic acid or one of their salts having an acid reaction; in this case the catalyst of the first stage is preferably neutralized so as to form a sparingly-soluble salt, for instance by adding calcium or barium chloride in the case of sulphuric acid.  In the second stage there may be present in the reaction mixture the glycol corresponding with the oxide used.  In examples: (1) ethylene oxide is added to aqueous formaldehyde of 30 per cent strength containing a little sulphuric acid, the mixture being first cooled and then heated to 50-100 DEG  C.; the sulphuric acid is then removed by adding the equivalent quantity or an excess of calcium or barium chloride (whereby hydrochloric acid is liberated) and the mixture is passed into a distilling vessel partly filled with glycol or with a mixture of glycol and polyglycols obtained by treating ethylene oxide with water; the temperature is raised to 100-150 DEG  C.; (2) and (3) propylene oxide is reacted with aqueous formaldehyde in a similar manner; (4) ethylene oxide is reacted with aqueous formaldehyde in the presence of oxalic acid in the first stage and hydrochloric acid in the second, the oxalic acid being removed by calcium or barium chloride.
