Polymerization of ionic organic compounds for soluble high-molecular-weight polymersHaramoto, Yuichiro
就是这句话的解释:ionic compounds are often soluble in water because water is a polar molecule and is attracted to the ions.要的是解释不是翻译(不是很理解“water is a polar molecule and is attracted to the ions” 相关知识点: 试题来源: 解析 由离子构成的分子,遇水会进行离子的游离,与水中的H...
Sci. 26, compounds and polymersNo. 113, p.25-254 (1957)(18) W09723591 Anionic alkylbenzene sulfonate andnon-ionic surfactants in detergentcompositions containing PVP/PVIcopolymers ___ Accordingly, it is an object of this invention to provide laundry detergent compositions including a water soluble...
Composition No.3 (waste/binder): after enrichment waste and magnesia cement mixing, amoeboid compounds are formed as a result of the concentration of the magnesian component, which is 1% of the total volume of enrichment wastes from the water-soluble ores. Mineralized crystals of waste are cement...
pH, additives, time, temperature, cosolvents, and ionic strength will affect the solution conditions. Pharmaceutical compounds with poor water solubility can intensely decrease output in drug discovery and development. A“good compound” must reach the target site’s inactive focuses. Solubility of ...
11 12 Since water-soluble zinc salts are ionically bonded compounds consisting of cationic zinc and 13 acid residue anion(s), dissolution of these salts in aqueous media causes dissociation by 14 creating solvated zinc cations and respective anion(s). In the dissolved state, zinc and 15 anions...
Out of this list, which lipids can be considered glycolipids? Phospholipids? Which are ionic? I. fatty acids II. triacylglycerols III. glycerophospholipids IV. sphingolipids V. steroids VI. isoprenoidsWhich of the following options is correct? Monomers are...
[0027] In short, the variety and number of useful compounds is far too long to list, and it will be understood that any material or combination of material with sufficient material strength, optimal disintegration time frame within the body, and acceptable level of harmful side effects may be...
Particularly for compounds with poor aqueous solubility, the establishment of paediatric BCS could contribute to the: Overall, the development and validation of a pBCS, could improve and facilitate paediatric drug product development. However, current literature indicates that this classification system ...
The compounds may be sparingly soluble, slightly soluble, very slightly soluble, or insoluble in water. The following list of active pharmaceutical ingredients is suitable for delivery in the matrix fills described herein. A person of skill in the art would recognize additional suitable active ...
