    摘要： In a process for producing a hydrocarbon composition, a feed comprising at least one C3 to C8 olefin and an olefinic recycle stream rich in C9− hydrocarbons is contacted with a crystalline molecular sieve catalyst having an average crystal size no greater than 0.05 micron and an alpha value between about 100 and about 600 in at least one reaction zone under olefin oligomerization conditions including an inlet temperature between about 150° C. and about 350° C., a pressure of at least 2,860 kPa and a recycle to feed weight ratio of about 0.1 to about 3.0. The contacting produces an oligomerization effluent stream, which is separated into at least a hydrocarbon product stream rich in C9+ hydrocarbons and the olefinic recycle stream.

    摘要： In a process for making an N-substituted phthalimide compound, an amine is contacted with a carboxylic acid anhydride and allowed to react in an aqueous solution at a pH of about 2 to about 6. Optionally, the reactants are combined with an acid to lower the pH of the reaction solution wherein the lowering of the pH optimizes the yield of the desired N-substituted phthalimide product. The N-substituted phthalimide may be, for example, N-hydroxyphthalimide, and the reactants may be phthalic anhydride and hydroxylamine or a salt thereof. The N-substituted phthalimide compound is useful for, among other things, the oxidation of various hydrocarbons.
