Pyridine is a basic heterocyclic organic compound with the chemical formula C₅H₅N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom. It is a highly flammable, weakly alkaline, water-soluble liquid with a distinctive, unpleasant fish-like smell. Pyridine is colorless, but older or impure samples can appear yellow. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Historically, pyridine was produced from coal tar. Today it is synthesized on the scale of about 20,000 tonnes per year worldwide.
Method and apparatus for sequesting entrained and volatile catalyst species in a carbonylation process
A method and apparatus for sequestering entrained or volatile catalyst species in a carbonylation process includes contacting the product stream with a vinyl pyridine or a vinyl pyrrolidone resin bed which is operative to sequester entrained or volatile catalytic species. The invention is particularly useful in connection with the iridium catalyzed carbonylation of methanol wherein the loss of entrained or volatile catalyst species depletes the catalytic content of the reactor. The resin may be digested in order to recover the catalytic metals.

The present invention generally comprises a silicon dioxide atomic layer deposition method. By providing pyridine as a catalyst, water may be utilized as the oxidization source while depositing at a low temperature. Prior to exposing the substrate to the water, the substrate may be exposed to a pyridine soak process. Additionally, the water may be co-flowed to the chamber with the pyridine through separate conduits to reduce interaction prior to entering the chamber. Alternatively, the pyridine may be co-flowed with a silicon precursor that does not react with pyridine.

Method for manufacturing alkylate oil with composite ionic liquid used as catalyst
ActiveUS20040133056A1Increase contentRaise the ratioOrganic chemistry methodsLiquid hydrocarbon mixtures productionAlkaneIonic liquid
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.

Method for preparing methyl acetate by carbonylating dimethyl ether
ActiveCN101613274AImprove stabilityHigh activityOrganic-compounds/hydrides/coordination-complexes catalystsPreparation by carbon monoxide or formate reactionMolecular sieveMethyl acetate
The invention discloses a catalyst modification method for preparing methyl acetate by carbonylating dimethyl ether. The method is applied to the reaction process in which the dimethyl ether reacts with the carbon monoxide to high selectively form methyl acetate in the presence of an acid molecular sieve catalyst, particularly a mordenite molecular sieve. Pyridine organic amines are utilized to modify the mordenite molecular sieve and modify a channel structure and the acidity of the molecular sieve, thereby effectively inhibiting carbon deposition and greatly improving the stability of catalysts. The use of the catalysts by the method can catalyze the carbonylation of dimethyl ether to obtain methyl acetate under mild conditions. The conversion rate of dimethyl ether is between 10 and 60percent, the selectivity of the methyl acetate is over 99 percent, and the activity of the catalysts is kept steady after the reaction is performed for 48 hours.
