hydroxyl

Methane reacts with hydroxyl to produce formaldehyde.

The hydroxyl value analysis of acrylate-styrene copolymcr solution by usillg acetylchloride as an acetylating agent is discussed.

Glycolipids (glycosyldiacylglycerols) are diacylglycerols with a sugar attached to the unesterified hydroxyl group.

METHODS The hydroxyl groups of magnolol were protected using ketol reaction and the products were purified by recrystallization from hexane.

The results show that, after thermal treatment, the quinonoid structure is formed and the conjugated carboxide and phenolic hydroxyl are increased;

In this paper, synthesis of salidroside was reported starting from 4 hydroxyl phenylacetic acid through benzylation, esterification, reduction and glycosidation.

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.

hydroxyl ketene dithioacetals possessing an allylalcohol moiety, as well as terminal bisalkylthio substituted alkene are a class of important intermediates in organic synthesis.

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.

The hydroxyl value of epoxy-containing polyester was determined by analyzing acetification principle and using acetyl chloride as acetifier and methylene chloride as solvent.

Analysing the relationship between substitutes, crosslinking structure and excited state,it was found that amidocyanogen and hydroxyl can reduce the bad gap, especially amidocyanogen;

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.

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 .
