Synthesis of polyethenoxyether phosphate using polyethenoxyether as initiator and using phosphorus pentoxide as parkerizing reagent, and its application were studied.
Three strategies (additive, chiral auxiliary or chiral reagent) were developed to improve the diastereoselectivity or enantioselectivity of the ylide cyclopropanation reactions.
The effects of reactant ratio, reaction time, catalyst amount,the species and amount of deaquation reagent on the yield of benzaldehyde 1,3-butanediol acetal were investigated.
The selective oxidation of ethers by chromic reagent, peroxide, nitric acid, oxygen and ozonide, as well as the ethers anodic oxidation are particularly introduced.
Research and development for fhe production of pyrocatechol and hydroquinone by reaction of phenol with hydrogen peroxide and percarboxylic acid as hydroxylating reagent are introduced.
Objective To discuss the biurea method for determination of total protein in serum of fat emulsion specimens with double reagents on the automated biochemical analyzer.
A series of reversible thermochromic paints were prepared using different kinds of inorganic compounds as filler,cresol red as chromophoric reagent and boric acid as delomorphic reagent.
A new mathod is studied for the synthesis of diketones with the crosscoupling reaction of organotin reagents and diacyl chlorides catalyzed by cellulose oxyphosphine palladium complex compound.
The catalyzed asymmetric synthesis was the effective method to prepare the optics active compounds, the pentamethide obtaines the widespread application as the reagent or the catalyst in this domain.
Pyridine can react with halogens,nitronium fluoroborate, sulfur trioxide, boranes and chromium trioxide to form some useful organic reagents which are introduced briefly in the paper.
This is a way of joining two molecules into a six-carbon ring. One of the reagents contributes four carbon atoms to the ring and the other contributes two.
If the environment being spread through is an animal embryo and the reagents are hormones that trigger the differentiation of the body's pigment-producing cells, the upshot is a distinct pattern of pigmentation.
