Title: Production of salts of sulphonic acids
IPC: C07C309/31
Filed: 1954-04-07
Abstract: A salt of a sulphonic acid of a hydrocarbon substantially free from organic solvent-insoluble salts is prepared by the reaction of a hydrocarbon with sulphur trioxide under substantially anhydrous conditions to produce a crude reaction product which is substantially free from uncombined sulphur trioxide, and subsequent neutralization of the product, a mono- or poly-hydric alcohol being added to the crude reaction product after substantial completion of the reaction between sulphur trioxide and hydrocarbon, and reaction therewith being allowed to occur prior to completion of the neutralization thereof.  Specified hydrocarbons which may be sulphonated are olefins containing 8-30 carbon atoms such as hexadecene-1, tetradecene, octadecene and octadecadiene and alkylated aromatic hydrocarbons such as alkylated benzenes, diphenyls and naphthalenes.  Alkyl benzenes containing 10-15 or 18-30 carbon atoms in the alkyl group are preferred.  Organic amines or inorganic alkalis may be used for the neutralization.  Specified alcohols are methyl, ethyl, propyl, butyl, amyl, hexyl, heptyl, octyl, 2-ethylhexyl, nonyl, decyl, undecyl, lauryl and tetrahydrofurfuryl alcohols; ethylene and propylene glycols, glycerine and 2-ethyl-hexanediol-1 : 3; diethylene and dipropylene glycols, ethylene glycol mono-butyl or mono-methyl ether and diethylene glycol mono-methyl or mono-ethyl ether; and the reaction products of ethylene oxide and furfuryl, tetrahydrofurfuryl, octyl, nonyl, decyl, undecyl, dodecyl or oleyl alcohol, phenol, tall oil, or decyl or dodecyl mercaptan. In examples: (1) a "keryl" benzene (mainly dodecyl benzene) is sulphonated by passing sulphur trioxide and air, the product is neutralized with aqueous caustic soda or reacted with lauryl alcohol, methanol, glycerol, 2-ethyl-hexanol or a tall oil-ethylene oxide condensate and then neutralized and the amount of alcohol-insoluble matter in the final products is compared; (2) as in (1) but adding 90 per cent of the monobutylamine required for neutralization to the sulphonation mass, adding a tall oil-ethylene oxide condensate, reacting, and completing the neutralization with monobutylamine; (3) as in (1) using methanol; (4) an alkyl benzene having 20-24 carbon atoms in one or two alkyl groups is sulphonated as in (1) and reacted with methanol before neutralization with sodium hydroxide; (5) as in (1) using n-propanol. Specification 705,117, [Group III], is referred to.
