Synthesis of epoxy plasticizers – ZhangJia Gang YaRui

Synthesis of epoxy plasticizers. The synthesis method of epoxy plasticizer is introduced in this paper. The synthetic method of epoxide plasticizer is based on the chemical method for the synthesis of epoxide oil. The principle is that organic acids (usually formic acid or acetic acid) react with hydrogen peroxide to form peroxic acid under the Nitrate ion-selective electrodes based on quaternary Nitrate ion-selective electrodes based on quaternary phosphonium salts in plasticized poly(vinyl chloride) and influence of membrane homogeneity on their

The influence of the plasticizer in the PVC membrane on the selectivity pattern of the CHEMFET for the detection of nitrate has been investigated Effect of Ionic Radius in Metal Nitrate on Pore Generation Thus, it could be thought that the Cd(NO 3) 2 ·4H 2 O salt played a role as a stronger plasticizer than the other metal nitrate salts such as Ni(NO 3) 2 and Mg(NO 3) 2. These results were attributable to the fact that the atomic radius and ionic radius of the Cd were largest among the three elements, resulting in the relatively larger Cd of the Cd(NO 3 ) 2 that could easily be dissociated

Nitrate ion-selective electrodes based on quaternary

Nitrate ion-selective electrodes based on quaternary phosphonium salts in plasticized poly(vinyl chloride) and influence of membrane homogeneity on their Chemically modified field effect transistors with nitrite or Also the sensitivity and selectivity of the fluoride selective CHEMFETs is better with the polysiloxane membranes than with plasticized PVC membranes. Even in the presence of 0.1 M of the more lipophilic chloride, bromide, or nitrate ions an almost Nernstian response and a detection limit of 0.25 m M is obtained for fluoride (log K F, j Pot = –2.5).
