ABSTRACT:
There are disclosed novel compositions of matter comprising monoalkylphenols prepared by selectively alkylating the olefin component of a thermally cracked sulfur-containing petroleum distillate derived from residua. The monoalkylphenols have certain ortho to para ratios and may be used to prepare a number of useful derivatives such as ethoxylated and propoxylated surfactants, sulfoalkylated products, sulfurized antioxidants, overbased phenates, dithiophosphate derivatives, formaldehyde reaction products and similar methylene bridged products which are useful demulsifiers.
