| titleOfInvention | Improvements in the production of neutral inorganic esters of polyglycol ethers |
| abstract | Condensation products (esters) are made by heating about 2 mols. of polyglycol ethers of formula A-(OC2H4)n-B, wherein A is an aliphatic, cycloaliphatic, aromatic or heterocyclic radicle of 3-23 C atoms, B is OH or OMe (Me representing an alkali metal) and n is not more than 2, with one mol. of a dibasic inorganic acid which does not contain carbon, or a halide thereof, or by heating about 2 mols. of a compound of the above formula wherein A and n are as stated but B is halogen, -OSO3H or -OSO3Me (Me being a metal atom) with one mol. of an alkali metal sulphide. Polyglycol ethers specified are propyl- and amyl-hexaglycol ether, dodecylnonaglycol ether, octadecyldecaglycol ether, oleyldodecaglycol ether, lauric acid octaglycol ether, butyric acid ethanolamide decaglycol ether, palmitylaminononaglycol ether, cyclohexanolhexaglycol ether, phenolpentaglycol ether, hexylpeptylnaphtholdecaglycol ether, benzoic acid octaglycol ether, salicylic acid pentaglycol ether, furfurylpentadecaglycol ether and pyridine carboxylic acid octaglycol ether. Symmetrical or mixed esters may be obtained. They are wetting and dispersing agents and some are anaesthetics. In examples: (1) dodecylnonaglycol ether is treated with sulphuryl chloride in benzene to yield di-dodecylnonaglycol sulphate, and (2) dodecylnonaglycol bromide is heated under pressure with sodium sulphide in aqueous methanol to yield di-dodecylnonaglycol thioether. |
