CL/OH molar ratio

Figure 14 shows the dependence of the Tg of CAPCL samples on the CL/OH molar ratio. It is known that dry cellulose does not present glass transition in the temperature range from 20 °C to the thermal decomposition temperature. When cellulose is acetylated, the glass transition is observed... 

When the DSC curves were magnified, the two baseline deviations due to the glass transitions of CA and PCL were clearly observed. The glass transition of CA can be observed at low CL/OH molar ratio and becomes very difficult to detect when this ratio exceeds 8. The Tg of CA decreases on increasing the CL content, very likely because the introduction of large side chain molecules gives rise to intermolecular distances expansion the increased free space enhances the main chain motions. The glass transition of PCL is observed at about -50 °C the Tg decreases at low CL/OH molar...

Monoester salts of phosphoric acid derived from fatty alcohol ethylene oxide adduct or alkylphenol ethylene oxide adduct useful as surfactants are prepared by addition of R(OCH2CH2) OH, alkali fluoride and (C12P0)20 in a molar ratio of 0.9-1.5 0.05-1 1.0 at -50 to + 10°C and hydrolysis of the Cl-containing intermediates with a base. The monoester phosphates showed comparable or better washing and foaming efficiency than commercial products [12].

The diastereomeric purities of 2a were determined by capillary gas chromatography or H-NMR studies (quantitative determination of the molar ratio 2a/2b). The enantiomeric purities of 2a were established, affer derivatization with (S)-2-methoxy-2-(trifluoromethyl)-2-phenylacetyl chloride [(5)-MTPA-Cl], by H- or F-NMR studies [quantitative determination of the molar ratio (Si5, C7 )-2a/(SiR,CS)-2a]. The enantiomeric purities of 3a (after hydrolytic conversion into 2a) were determined analogously to those of 2a. The absolute configurations at the SiCH(OH)C carbon atoms of the enantiomers of 2a were established, after derivatization with (5 -MTPA-Cl, by the NMR-spectroscopic correlation method described in [7]. The relative configurations of 2a and 2b were assigned by comparison with the diastereoisomers of 1-methyl-1-phenyl-l-sila-2-cyclohexanol (in this context, see [8]). 

Cl)3Cl6(thf)3 with NaOPr in 1 6 molar ratio in THF and isolated the X-ray crystallographically characterized " green complex Re3(/r-OPr )3(OPr )6.iPr OH in a very low (18%) yield. Naturally the unreacted Resl/r-COsClftlthOs had to be removed from the reaction medium. 

Zirconium hydroxy oxychloride [18428-88-17, nominally ZrO(OH)Cl, is produced by dissolving hydrous zirconia in hydrochloric acid in an equal molar proportion, and is available only in solution. Other oxychlorides with Cl Zr ratios <2 are discussed in Reference 199. 

The XRD analyses of the solid phase are shown in Fig. 2. When the additive ratio of CaCr04 in molar was below 1.0, the peaks of Cl-HC were decreased with increases in the additive ratio of CaCr04, and the peaks of Ca4Ah(OH) 12- Cr04- 6H2O and...
