3.In this paper, synthesis of salidroside was reported starting from 4 hydroxyl phenylacetic acid through benzylation, esterification, reduction and glycosidation.
4.The hydroxyl value of epoxy-containing polyester was determined by analyzing acetification principle and using acetyl chloride as acetifier and methylene chloride as solvent.
5.The ring-opening polymerization mechanism of lactide in the presence of hydroxyl compounds was studied by using ferric ethoxide and ferric n-butoxide as catalysts respectively.
6.Acylation activity of hydroxyl groups in methyl cholicate has been determined by the use of methacryloyl chloride, methacryloyl anhydride and methacrylic acid as the acylating agents.
7.Nuclear magnetic resonance techniques are used to determine the national aleutric acid preferential conformation. The results show that the dithionic hydroxyl radicals are in reciprocal cross bearing.
8.The aurone compounds are generally on one plane ,and they have a bigger conjugate system .The inducement of hydroxyl substituents has little influence on their own geometries .
4.Normally, dehydration would make tardigrade DNA susceptible to damage from chemicals called hydroxyl radicals, which form when water molecules split.
9.Their experiments show that methanol, commonly known as wood alcohol, and hydroxyl react rapidly at –210 degrees Celsius to form methoxy, which has also been spotted in space.
11.Carboxylic acids are a type of organic compound characterized by a carbon (C) atom doubly bonded to an oxygen (O) atom and singly bonded to a hydroxyl group (-OH) .
12.Beta hydroxybutyric acid on the other hand, even though it's still one of the ketone bodies, isn't technically a ketoacid since its ketone group has been reduced to a hydroxyl group.
13.If you were paying attention, you learned that alcohols are organic compounds with hydroxyl groups, if you dehydrogenate them, the hydroxyl converts to a carbonyl and they become dehydrogenated alcohols or aldehydes.
14.Technically speaking, an alcohol is any compound that contains a hydrogen-oxygen pair, known as a hydroxyl group, that's bound to an atom of carbon that's saturated, meaning all of its electrons are bound to something else.
15.It replaced one of salicylic acid's hydroxyl group — that's an oxygen and hydrogen bonded to a carbon — with an acetyl group, which is two carbons, one double-bonded to an oxygen and the other bonded to three hydrogens.
16.If it's a six carbon chain with a carboxylic acid on it and an alcohol on one of the other carbons, our name has to do two things: identify that the hydroxyl group is there and identify where it is.
