This condensed evaporative flux corresponded to a fraction of the total evaporative flux, which was determined by calculation from the registered relative humidity values. Two different sets of experiments were carried out with changes in the DMI compositions, one with 10% and the other with 33%....
The crystals formed are isolated by filtration and then purified on a column of silica (Merck 9385®), using a mixture of dichloromethane and acetone (4:1 V/V) as elution solvent, to obtain pure 7-[2-{4-[(2,3,4-trimethoxyphenyl)methyl]-1-piperazinyl}-2-oxoethoxy]-5-hyd roxy-4'...
Consequently, the electron-rich aldehydes coordinate better and thus promoting the attack of amine to the carbonyl carbon which results in the production of two-fold condensation products in higher yields and mono-condensed products in lower yields. However the aldehydes with EWGs do not coordinate ...

maintaining a mesh-like chromatin structure (Fig.4A). This trend was consistently observed in multiple fields in different independent experiments. In contrast, H2O2-treated cells displayed the typical hallmarks of apoptotic nuclei, i.e. condensed and fragmented chromatin material. In accordance with ...
or desirably the methyl or ethyl ester, may' be employed, or the acyl halide such as the" acyl chloride, or the acid anhydride; "The resulting mono-acyl amino derivative is then condensed with the aid of a suitable mild dehydrating agent, such as powdered calcium oxide, to form the 2-...
which is subsequently chlorinated. In the second process, phenol is chlorinated, generating 2,4-dichlorophenol, which is subsequently condensed with chloroacetic acid. The butyl ester derivative of 2,4-D is produced by the esterification of the acid with butanol in the presence of a ferric chlorid...
