    摘要: Severely sterically hindered secondary aminoether alcohols are prepared by reacting organic carboxylic, organic carboxylic acid halides, acid anhydrides or a ketene with an alkyl, alkaryl or alkylhalo sulfonate to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then animated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.

    摘要: A heavy lubricant base stock is made by (a) producing a synthesis gas from natural gas, (b) reacting the H2 and CO in the gas in the presence of a cobalt Fischer-Tropsch catalyst, at reaction conditions effective to synthesize waxy hydrocarbons boiling in the heavy lubricant oil range, which are hydrodewaxed it at least two stages, with interstage separation and removal of the lighter material.
