The dyes with donor π conjugated bridge acceptor(D π A) structure exhibit a good photoelectric conversion property and excellent second order nonlinearity because they can cause photoinduced intramolecular electron transfer along π conjugated bridge.
By adding activated charcoal into the bioreactor,the conversion rate was raised to 1.09%,the maximum vanillin concentration was 136.48 mg/L in receiving solution,and vanillin amounted to 96.77% of the total area of the HPLC peaks.
Polystyrene film encapsulated on the surface of flaky aluminium of micro-particles was prepared by in situ polymerization. The conversion of monomer(C%),the percentage of grafting(PG%),and the grafting efficiency(GE%) were discussed.
The experimental data show that when the initiator is ammonium ceric nitrate and the inter-crosslinker is divinylbenzene in the preparation of polyurethane-polyether,the amount of initiator is 1.00% of total monomers mass,the ratio of polyurethane-polyether to acrylic resin is 15 ∶1,the resins have high conversion and the coating prepared has excellent hydrophilicity.
But there appeared to be species difference in arteether metabolism, highest conversion being recorded with humans followed by rats and monkeys.
Aldose reductase (AR) is an enzyme that catalyzes the conversion of glucose to sorbitol, which is in turn converted to fructose by sorbitol dehydrogenase.
The conversion of CNB could reach 99.9%, and the dechlorination of chloroaniline (CAN) was less than 1.9% when catalyzed by Pt-Sn-B/CNTs and more than 8.0% when catalyzed by common hydrogenation catalysts.
Results show that HY is an efficient catalyst for the acetalization and ketalization with high conversion and selectivity in mild conditions.
Under these conditions, the conversion and selectivity were over 50% and 97%, respectively.
