An alkyl amine is a compound that has an alkyl group attached to the nitrogen atom of an amine. Alkyl amines arise when one of the three hydrogen atoms in ammonia is replaced by an alkyl.

Method for manufacturing alkylate oil with composite ionic liquid used as catalyst

The present invention pertains to a method for manufacturing alkylate oil using a composite ionic liquid as catalyst. A mixture of isobutane and C4 olefins is used as the raw material, and a composite ionic liquid is used as catalyst to carry out an alkylation reaction. The alkane / olefin ratio in the raw material is higher than 1:1. In the composition of the aforementioned composite ionic liquid catalyst, the cations come from a hydrohalide of an alkyl-containing amine or pyridine, while the anions are composite coordinate anions coming from two or more metal compounds. One of the metal compounds is an aluminum compound, while other metal compounds are compounds of Group IB and Group IIB elements of the Periodic Table and the transition metals. The present invention also provides a design of static mixer reaction apparatus that can realize the aforementioned manufacturing method. The method of the present invention increases the selectivity of the alkylation reaction to give the alkylation product a relatively high octane number and further increase the product yield. Also, the manufacturing operation is simplified, and the cost can be reduced. This method is an environmentally friendly method that will not pollute the environment.

Methods of chemically derivatizing single-wall carbon nanotubes

This invention is directed to making chemical derivatives of carbon nanotubes and to uses for the derivatized nanotubes, including making arrays as a basis for synthesis of carbon fibers. In one embodiment, this invention also provides a method for preparing single wall carbon nanotubes having substituents attached to the side wall of the nanotube by reacting single wall carbon nanotubes with fluorine gas and recovering fluorine derivatized carbon nanotubes, then reacting fluorine derivatized carbon nanotubes with a nucleophile. Some of the fluorine substituents are replaced by nucleophilic substitution. If desired, the remaining fluorine can be completely or partially eliminated to produce single wall carbon nanotubes having substituents attached to the side wall of the nanotube. The substituents will, of course, be dependent on the nucleophile, and preferred nucleophiles include alkyl lithium species such as methyl lithium. Alternatively, fluorine may be fully or partially removed from fluorine derivatized carbon nanotubes by reacting the fluorine derivatized carbon nanotubes with various amounts of hydrazine, substituted hydrazine or alkyl amine. The present invention also provides seed materials for growth of single wall carbon nanotubes comprising a plurality of single wall carbon nanotubes or short tubular molecules having a catalyst precursor moiety covalently bound or physisorbed on the outer surface of the sidewall to provide the optimum metal cluster size under conditions that result in migration of the metal moiety to the tube end.

Microbial process for the preparation of acetic acid as well as solvent for its extraction from the fermentation broth

A modified water-immiscible solvent useful in the extraction of acetic acid from aqueous streams is a substantially pure mixture of isomers of highly branched di-alkyl amines. This solvent is substantially devoid of mono-alkyl amines and alcohols. Solvent mixtures formed of such a modified solvent with a desired cosolvent, preferably a low boiling hydrocarbon which forms an azeotrope with water are useful in the extraction of acetic acid from aqueous gaseous streams. An anaerobic microbial fermentation process for the production of acetic acid employs such solvents, under conditions which limit amide formation by the solvent and thus increase the efficiency of acetic acid recovery. Methods for the direct extraction of acetic acid and the extractive fermentation of acetic acid also employ the modified solvents and increase efficiency of acetic acid production. Such increases in efficiency are also obtained where the energy source for the microbial fermentation contains carbon dioxide and the method includes a carbon dioxide stripping step prior to extraction of acetic acid in solvent.
