The present invention relates to the field of water-soluble or water-dispersible copolymers with a neutral or near-neutral pH, that is to say between 5.5 and 9.5, comprising at least one random copolymer comprising methacrylic acid, at least one butyl acrylate, styrene and a monomer selected ...
WATER-SOLUBLE COBALT CATALYSTS, PROCESS FOR THEIR PREPARATION AND THEIR USE AS HYDROFORMYLATION CATALYSTS IN A TWO-PHASE SYSTEM WITH POLYETHYLENE GLYCOL AS THE POLAR PHASE Co carbonyl catalysts of formula (I): (I); in which R = -CH(CH2OCH2CH2)2 or - C2H4(OCH2CH2)n OY in which n = 1...
Effects of water-soluble co-solvents(WSCs)on the properties of water/oil Pickering emulsions were investigated. Pickering emulsions were prepared in the system of 1,2,4-trimethylbenzene(TMB)/ hydrophobic silica/ water with varied concentrations of WSCs(ethanol, acetic acid and glycerin). Mean dropl...
Solubilization of metronidazole by water-miscible multi-cosolvents and water-soluble vitamins. In the systemic treatment of anaerobic infections, a parenteral mode of administration of metronidazole is preferable. The practical way of administering a parenteral dose (500 mg/dose) of metronidazole in a ...
water and groundwater systems via run-off, direct discharge, accidental spillages, infiltration, recharge, and surface water-groundwater interactions (Gwenzi and Chaukura2018). For instance, various pharmaceutical drugs such as antibiotics were detected up to mg L−1in groundwater in Germany (...
water-soluble or water-swellable polymers as such, which can be obtained according to said process, to their use in the hygiene industry, packaging industry, in the agrarian technology or in agriculture and horticulture, in the cable industry and information technology, in the food industry, ...
The solubilities of three poorly water soluble drugs, phenytoin, diazepam and benzocaine, were measured in various cosolvent-water mixtures. The data were generally described by the relationship: log (S(m)/S(w)) = Σfσ where S(m) is the solubility of the drug in the cosolvent-water mixtu...
Water-soluble 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (dmoPTA) as a polydentate ligand: synthesis of [RuClCp(PPh3)-mu-dmoPTA-1kappaP:2kappa2N,N'-Co(acac-kappa2O,O')2].H2O The dinuclear complex [RuClCp(PPh3)-mu-dmoPTA-1kappa P:2kappa(2)N, N'-Co(acac-kappa...
Curcumin was purchased from Beijing Huafeng Lianbo [molecular formula C21H20O6, molecular weight 368.39, orange-yellow crystalline powder, solubility: soluble in ethanol, propylene glycol, acetone, glacial acetic acid and alkaline solution, soluble in ethanol, soluble with water, insoluble in cold ...
Point-zero-eight moles of NaOH were dissolved in 100 mL degassed deionized water. The reaction solution was mechanically stirred at 500 rpm while nitrogen gas flowed into the flask. After charging of the reactor with NaOH was completed, stirring continued for 3 h, after which the final pH ...
