Synthesis and paste properties of octenyl succinic anhydride modified early Indica rice starch
Octenyl succinic anhydride (OSA) modified early Indica rice starch was prepared in aqueous slurry systems using response surface methodology. The paste properties of the OSA starch were also investigated. Results indicated that the suitable parameters for the preparation of OSA starch from early Indica rice starch were as follows: reaction period 4 h, reaction temperature 33.4 °C, pH of reactio...
متن کاملSynthesis of Novel Sterically Demanding Carbo- and Heterocyclic β-Ketoesters
We present an easy method for the synthesis of β-ketoesters starting from various carbocyclic and heterocyclic carboxylic acids and esters. The β-ketoester side-chain was introduced by a sequence involving α-deprotonation and quenching with CO2, conversion to the corresponding acid chloride and subsequent chain elongation using deprotonated ethyl acetate.
متن کاملAdsorption of cytochrome c by succinic anhydride-modified peanut shells
A novel adsorbent based on peanut shells modified with glutaraldehyde and succinic anhydride was prepared. Factors affecting the adsorption capacity, such as the pH, temperature, adsorption time, initial cytochrome c (cyt c) concentration and NaCl ionic strength, were extensively investigated. The results showed that the maximum adsorption capacity of the modified peanut shells (MPSs) was 432.6...

15 صفحه اولSynthesis and characterization of a novel dialdehyde and cyclic anhydride.
The acid treatment of a ruthenabenzene yielded an unusual dialdehyde. Interestingly, this dialdehyde has notable anti-oxidative properties and resists even nitric acid. This stability is confirmed by chemical and electrochemical experiments. In addition, a stable cyclic anhydride is synthesized from the dialdehyde via an environmentally friendly electrochemical method.
