phenolic hydroxyl-containing organic compound is selected from the group consisting of glycerine, pentaerythritol, trimethylolpropane, trimethylolethane, dipentaerythritol, neopentylglycol, cyclohexanedimethanol, ethylene glycol, diethylene glycol, triethylene glycol, and diols of the formula HO--C2-36 alkylene...
Cells were lysed in 1 ml lysis buffer (20 mM Tris HCl, pH 7.4, 137 mM NaCl, 2 mM EDTA, 10% glycerine, 1% Triton X-100, 1 mM PMSF, Protease Inhibitor mix (Roche, Penzberg, Germany)) for 30 min on ice and subsequently centrifuged for 15 min at 13 000 r.p.m. In all, 50 ...
We present the relaxation dynamics of glass-forming glycerol mixed with 1.1 nm sized polyhedral oligomeric silsesquioxane (POSS) molecules using dielectric spectroscopy (DS) and two different neutron scattering (NS) techniques. Both, the reorientational dynamics as measured by DS and the density fluctua...
1. The excess phenol and water is then removed by any conventional means such as by flashing under vacuum. Then the resultant novolac resin is reacted with an excess of an epihalohydrin such as epichlorohydrin or glycerine dichlorohydrin in the presence of a basic catalyst such as, for ...
Polymerization may be carried out at temperatures of - 30 DEG to 70 DEG C., and at the lower temperatures a freezing point depressant such as glycerine may be included in the aqueous medium. Specifications 656,727, 674,144, and 692,016, [Group III], are referred to....
The density and viscosity values of glycerol used in this study were obtained from the book of the Glycerine Producers Association [26], utilizing their values at a temperature of T = 25 °C. Meanwhile, the density and viscosity data for PEG 8000 were obtained from [25] at a temperature ...
It is a formula of 15 herbs in a 9:1 extract in a glycerine base that clears Heat and transforms Phlegm, supplementing the Spleen and fortifying Qi. Dosage: 1 to 2 droppersful for younger children, and 3 to 4 droppersful for older children. During an acute asthmatic episode, doses ...
isothiocyanate of the formula R(NCX)n, where R is an organic group, X is oxygen or sulphur and n is at least 2, with a polyalkylene glycol having a molecular weight of at least 200 in amount such that the ratio of -(NCX) groups to the OH groups contained therein is greater than ...
In order to introduce polyglycol or polyglycerine radicles into the mercaptans, the corresponding halogen compounds may also be employed. For example, one molecular proportion of a mercaptan may first be brought into reaction with several molecular proportions of epichlorhydrin and then with the ...
