Novel Reaction Scheme for the Selective Oxidation of o- Xylene to Phthalic Anhydride
The oxidation of o-xylene to phthalic anhydride is one of the important industrial processes based on selective oxidation reactions. For the last 50 years vanadia titania catalysts have been used in this process. The reaction parameters like temperature range of operation, reactor inlet pressure, contact time, etc. slightly changed during this continuous process optimization. However, the funda...
متن کاملReaction of myoglobin with 3,3-tetramethyleneglutaric anhydride.
1. The extent of reaction of the protein with 3,3-tetramethyleneglutaric anhydride was measured by determining the loss of lysine and the equivalent appearance of 3,3-tetramethyleneglutarimidolysine in the hydrolysate at various time-intervals. Of the 19 lysine residues in sperm-whale myoglobin, three did not react with 3,3-tetramethyleneglutaric anhydride. Also, the N-terminal valine did not r...
متن کاملN-Methylimidazole Promotes the Reaction of Homophthalic Anhydride with Imines
The addition of N-methylimidazole (NMI) to the reaction of homophthalic anhydride with imines such as pyridine-3-carboxaldehyde-N-trifluoroethylimine (9) reduces the amount of elimination byproduct and improves the yield of the formal cycloadduct, tetrahydroisoquinolonic carboxylate 10. Carboxanilides of such compounds are of interest as potential antimalarial agents. A mechanism that rationali...
متن کاملPolycondensation of Tetrahydrofuran with Phthalic Anhydride Induced By a Proton Exchanged Montmorillonite Clay
“Maghnite” a montmorillonite sheet silicate clay, exchanged with protons to produce “H-Maghnite” is an efficient catalyst for polymerization of many vinylic and heterocyclic monomers (Belbachir, M. U.S. Patent. 066969.0101 –2001). The structure compositions of both “Maghnite” and “H-Maghnite” have been developed. This catalyst was used for the polycondensation of the tetrahydrofuran with phthal...
متن کاملDMAP-CATALYZED PHTHALYLATION OF CELLULOSE WITH PHTHALIC ANHYDRIDE IN [bmim]Cl
It has been generally accepted that some ionic liquids are good media for homogeneous functionalization of cellulose. However, phthalylated cellulosic derivatives prepared in ionic liquids without any catalyst have lower DS as compared to the acetylated ones. In order to prepare the phthalylated cellulosic derivatives with higher DS, chemical modification of sugarcane bagasse cellulose with pht...
