Water is a polar solvent and when any ionic compound is dissolved in water the original structure of that compound is broken and separate ions are formed. Hence, the solubility of an ionic compound in water depends upon its hydration energy and lattice energy. Hydration energy refers to the en...
After intravenous administration, isavuconazonium is quickly hydrolyzed completely by plasma esterases, predominately by butylcholinesterase, to a benzyl alcohol, which undergoes an intramolecular cyclization and N-dealkylation to isavuconazole and an inactive cyclic by-product (also referred to as BAL...
A thixotropic coating composition for magnetic recording tapes comprises magnetic oxide particles, a binder of polyvinyl-butyral containing 5-17% by weight polyvinylalcohol, and a non-polar solvent, the particle: binder weight ratio being 2 : 1 to 10 : 1. Suitable solvents are methyl isobutyl ...

The hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen bonds with water and enhances the solubility of an alcohol in water. Which of the following is the most soluble in water? Methanol would have the highest solubility in water since it ...

a9) Rinse the collected pseudoephedrine in dry acetone. Dissolve in hot dry isopropyl alcohol and recrystalize with dry acetone as a second solvent. Repeat the recrystalization. 9) 冲洗收集的伪麻黄碱在干燥丙酮。 溶化在热的干燥异丙醇并且recrystalize与干燥丙酮作为第二种溶剂。 重覆recrystalization。[...
In this process, the fat or oil is first purified and then reacted with an alcohol, usually methanol (CH3OH) or ethanol (CH3CH2OH) in the presence of a catalyst such as potassium hydroxide (KOH) or sodium hydroxide (NaOH). When this happens, the triacylglycerol is transformed to form este...
, an aliphatic hydrocarbon (such as cyclohexane or paraffin wax (such as a mineral oil fraction)), an alcohol (such as butanol, ethylene glycol, and an ether or a ester thereof, etc.), a ketone (such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, etc.), a ...
