TOF values for dichloromethane HDC increased with increasing mean metal particle size within the range of this work (approximate to 1.2-2.3 nm). The catalysts with Pt:Pd molar ratios of 1:3 and 1:1 showed significantly better performance than the 3:1 one for overall dechlorination due to ...
(Z)-3-[2-(2,4-Dinitrophenyl)hydrazin-1-ylidene]isobenzofuran-1(3H)-one dichloromethane hemisolvate In the title compound, 2C14H8N4O6·CH2Cl2, the di-chloro-methane solvent mol-ecule resides on a crystallographic twofold axis. The mean plane of the phthal... P Agarwal,P Mishra,N Gu...
dichloromethaneweight fractionIn this article, seven relationships that have been widely used to estimate the dependence of apparent partial specific volume (APSV) with concentration are reviewed and compared with each other. Also, 10 methods to evaluate partial molar volume (PMV) were derived and ...
For isolation, the batch was cooled to RT, and the polymer was dissolved in 1000 ml of dichloromethane and then precipitated in 7.5 l of methanol with vigorous stirring. The precipitate was filtered off using a frit and then analyzed by means of GPC (Mn=23 500 g/mol, Mw/Mn=1.32). ...
The alkaloids were precipitated in the form of salt. The mixture was then filtered. The residue was taken, and ammonium hydroxide solution was added to maintain a pH of 10. The alkaline solution was subjected to solvent extraction with an equal volume of dichloromethane (DCM). The DCM layer ...
In the case of PP4, it was necessary to repeat the procedure with dichloromethane. The OIT of the industrial grade and after Soxhlet extraction are summarised in Table 2. Figure 4. Comparison of the OIT of the shredded PP granules. Table 2. OIT before and after Soxhlet extraction of the...
The weight loss measurement method was used to evaluate the adsorption isotherms where the fraction of surface coverage (θ) and inhibitor concentration were used. In this experiment, the molecular weight of the alkaloid Lycopsamine was used as a reference to calculate the molar concentration of ...
