氢化

Maleic Anhydride is important organic raw material and the third biggest acid anhydride next to benzene anhydride and acid anhydride. In recent years, Maleic Anhydride is esterified and hydrogenised under pressure to make 1,4- butanediol butylene glycol, and it is also hydrogenised to tetrahydrofuran, which enables Maleic Anhydride to become the raw material for producing high-value-added products and to be more widely applied.

Tetrachloroterephthalic acid was prepared by chlorinating terephthalic acid, oleumsolvent and iodine catalyst. Tetrachloroterephthalic acid was acylated by sulphurous oxychloride in the presence of DMF to form tetrachloroterephthaloyl chloride. The acyl chloride product was fluorinated by potassium fluoride and esterified by methanol to synthesize dimethyl tetrafluoroterephthalate. The ester was reduced with potassium borohydride and lithium chloride to give tetrafluoroterephthalyl alcohol. The above product was bromated in the hydrobromic acid to obtain 4-bromomethyl-2,3,5,6-tetrafluoro-benzene methanol. 4-Methyl-2,3,5,-6-tetrafluorobenzene ethanol was obtained by reducing the bromide with magnesium. In the exist of DCC and DMAP, tefluthrin was got by the condensation reaction between 4-methyl-2,3,5,6-tetrafluoro-benzene methanol and-(1RS,3RS)- 3-(2- chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropanecar-boxylate acid.

The discussions which the study investigated were chicken and pork meat processing for elders via different tender mode. In this study, we want to evaluate the nutritions of elders and focus on animal protein. The experiment was injected marination with CaCl2, NaHCO3 and enzyme on pork and chicken meat quality traits. Treatment on the meat was analyzed proximent quality and textural properties by response surface stepwise regression. The best tender method was discovered the elder's sensory evaluation of different tender mode and observed degradation of myoglobulin by muscle tissue slice and SDS-PAGE (10%). The function of sous-vide cooking collocated with tenderization that was evaluated by textural properties and sensory evaluation. It looks for discussion about meat processing for elders.

The finding of the blue-shifted F-He-H... Y (Y=N〓, CO and He) systems, where the proton-donor was incapable of rehybridization, indicated that rehybridization is not a generally application driving force for the blue shift. There were other two novel blue-shifted systems discovered in this study. They were lithium bonding systems and dihydrogen bonding systems. On the basis of state-of-art NBO analyses and potential energy surface analysis, it was demonstrated that Pauli/nuclei repulsions cause the blue shift.
