| titleOfInvention | Antifoam agents for conditioning boiler feed water |
| abstract | Diethers of 1, 12-octadecanediol with 18-25 mols. of ethylene oxide may be prepared by heating the ingredients together at a temperature between 100 and 200 DEG C. in presence of an alkaline catalyst, e.g. sodium, potassium or calcium or hydroxides or oxides thereof. The products with or without other materials are useful for preventing foaming of aqueous liquids used for generating steam (see Group III). Specification 380,431 is referred to.ALSO:Diethers of 1.12 octadecanediol with 18-25 mols of ethylene oxide (see Group IV (a)) minimise the formation of foam in aqueous media used for steam generation. Up to 1 part/million of the boiler water is usually added. The ethers are preferably mixed with other water treatment chemicals. A composition described contains .5-3 per cent. of the ether; 30-60 per cent. of a tannin; 1-5 per cent. of glassy sodium phosphate and 30-60 per cent. of sodium carbonate. Specification 380,431 is referred to. |
