Hydrolysis of lanolin yields lanolin alcohols and lanolin acids. Epoxy resins diluents are typically formed by glycidylation of aliphatic alcohols or polyols. THP ethers derived from chiral alcohols form diastereomers. Esters are more polar than ethers but less polar than alcohols. Alcohols and organic acids join to form esters. PCC also converts suitable unsaturated alcohols and aldehydes to cyclohexenones. Both isomers are soluble in simple alcohols, ethers, and chloroform. Alkenes are precursors to aldehydes, alcohols, polymers, and aromatics. Sodium borohydride is soluble in protic solvents such as water and lower alcohols. Reagents are known that drive the dehydration of mixtures of alcohols and carboxylic acids. Other sugar alcohols include xylitol and sorbitol. Some species can metabolize pentose sugars such as ribose, alcohols, and organic acids. More complex alkylation of a alcohols and phenols involve ethoxylation. Neutral nucleophilic reactions with solvents such as alcohols and water are named solvolysis. These compounds consist of methanol, isoprene, acetone, ethanol and other alcohols.
