There is a district difference in the melting behavior of both salt forms, namely sulfate and phosphate (235–240 °C vs. 162–164 °C, respectively). The high melting point of HCQS over diphosphate and HCQ free base results in the high stability of HCQS. The high crystal lattice strength...

salt, with the proviso that the ratio of the alkali silicate to the poly-alpha-hydroxyacrylic acid is 1:0.5 to 1:18. The compsn. is used in washing up machines. It is highly effective, esp. against burnt proteinaceous food residues, lipstick traces, tea deposits, etc. It may contain ...

when the pressure reaches 0.7~0.8MPa, stop passing carbon dioxide, warming up to 140 to 180℃. After the reaction with water, sodium salicylate dissolved and decolorization, filtering, coupled with the sulfuric acid, namely precipitation salicylic acid, after filtering, washing and drying to obtain...
Cells were then stained with Oil red O using fast red AL salt as a substrate. Representative photographs (20x) of C3H10T1/2 cells stained for Oil red O (round cells) (d). Optical density measured by Metaview Image Analysis (Olympus Inc. USA) in RSG-treated cells with and without FO ...

Further, most of the adsorbed material could be removed by washing the clay–DNA complex with water. On the other hand, in the presence of 4 mM Mg2 + ions, nearly all of the added DNA was taken up by the clay from which only ∼ 7% was desorbable by water washing. Similarly, ...
The reaction of a carboxylic acid with this reagent leads to acid anhydride if the transacylation equilibrium (equation 35) can be shifted to the side of the anhydride. This is possible either if the acid is used in twofold excess and forms an insoluble salt with the liberated imidazole or ...
