| titleOfInvention | Improvements in sulphonated alkylated aromatic ethers |
| abstract | 505,769. Making dispersions; colloidal sols. ROHM & HAAS CO. Nov. 16, 1937, No. 31447. Convention date, Dec. 30, 1936. [Class 1 (i)] [Also in Group IV] Ethers having the formula AROR<1> (OH)x, wherein A is an alkyl radicle containing at least eight carbon atoms, R is a benzene or naphthalene nucleus, R<1> is an alkyl radicle containing at least two carbon atoms or a polyalkyleneether group, and x is 1 or 2 are treated with sulphonating agents sufficient in quantity, to sulphonate the nucleus in addition to esterifying the hydroxy group or groups. The products, which may be neutralized with alkalies, ammonia, amines, hydroxyamines or quaternary ammonium bases are dispersing- and emulsifying agents and may be used for dispersing dyes, pigments, clays, - sulphur, zinc oxide and other insoluble powders. The nucleus R may contain halogen or nitro, acyl, alkyl, aralkyl, cycloalkyl or aryl groups as substituents. In examples : (1) p : : alpha alpha : gamma : gamma-tetramethylbutylphenoxyethanol, hexadecylphenoxyethanol, octadecylphenoxyethanol, tert : octyl-#-naphthoxyethanol and #-(p-alpha :alpha : gamma : gamma - tetramethylbutylphenoxy) - #<1>- hydroxydiethylether are sulphonated with chlorsulphonic acid; (2) p-tert-dodecylphenoxypropanediol-1 : 2 is treated with sulphur trioxide in ethytenedichloride ; (3) phenol (1 mot) is condensed with di-iso-butylene (2 mols) and the product etherified by means of ethylenechlorydrin ; the resulting di-tert-octylphenoxyethanol is sulphonated with furning sulphuric acid. The sulphonation of p-tertoctyl-o-chlorphenoxyethanol, p-tert-octyl-o-acetylphenoxyethanol, p-tert-octyl-o-phenylphenoxyethanol and the #-mono (alpha : alpha: gamma : gamma - tetramethylbutylphenyl) ether of di or triethyleneglycol is mentioned. |
