摘要:
Provided herein are various methods for forming alkylaromatic sulfonate compositions and blended alkylaromatic sulfonate compositions, and such compositions themselves. The methods of various embodiments include obtaining a C8-C30 hydrocarbon mixture, optionally treating the mixture to concentrate the mixture in sulfonatable aromatics, and sulfonating the mixture to form the alkylaromatic sulfonates. The mixture or treated mixture may be blended with linear alkyl benzene (LAB) compositions and sulfonated, and/or the alkylaryl sulfonates may be blended with linear alkylbenzene sulfonate (LAS) compositions, to form the blended alkylaromatic sulfonates of some embodiments. These compositions and processes for making them may be tailored to serve a variety of end uses, such as detergents in cleaning solutions or for enhanced oil recovery operations, and/or as low foaming and/or hydrotropic additives in detergent formulations, and the like.

This invention relates to novel overbased and neutral oil soluble metal dialkaryl hydrocarbon sulfonate compositions possessing low viscosity and outstanding rust inhibiting as well as water demulsification properties. Also, this invention relates to oil soluble metal dialkaryl sulfonate compounds in which the alkyl substituents contain from eight to 18 carbon atoms and are bonded to the aryl nucleus through a secondary carbon atom. In one aspect, the present invention concerns metal dialkaryl sulfonate compositions containing at least 20 weight percent metal dialkaryl sulfonate compounds in which the alkyl substituents are straight chain and contain from about eight to about 18 carbsn atoms, the aryl moiety being selected from the group consisting of benzene, toluene, xylene, naphthalene and mixtures thereof. In another aspect, the present invention concerns oil soluble metal sulfonate compositions containing metal dialkaryl sulfonate compounds in which one of the alkyl substituents is a straight chain group and the other is a branched chain group, the aryl moiety being selected from the group consisting of benzene, toluene, xylene, naphthalene, and mixtures thereof. In still another aspect, this invention concerns oil soluble metal hydrocarbon sulfonate compositions containing a major amount of metal dialkaryl sulfonate compounds in which the alkyl substituents are straight chain and contain from about eight to about 18 carbon atoms, the aryl moiety being selected from the group consisting of benzene, toluene and xylene, and a minor amount of tetrahydronaphthalene sulfonate compounds, said conpositions being derived from hydrocarbon compositions prepared by the disproportionation of mono-n-alkaryl compounds using aluminum chloride and/or aluminum bromide as the catalyst.
摘要:
The present invention is an asphaltene dispersant containing an aromatic, a sulfonic acid head, and an alkyl tail containing 16 carbons or more and at least one branch of a methyl or longer alkyl. Preferably, the aromatic is a fused two ring aromatic and the tail is a two, branched alkyl tail of 30 carbons or longer.
