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.
Thanks to all the staff, SINNOWA has developed international-level fully automatic clinical chemistry analyzer, Coagulometer, Microplate Reader, Hematology Analyzer and diagnostic reagents.
The selective oxidation of ethers by chromic reagent, peroxide, nitric acid, oxygen and ozonide, as well as the ethers anodic oxidation are particularly introduced.
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.
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.
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.
Abstract: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.
To turn nasal spray into meth, you’d need to first break its very strong covalent bonds, and that requires dangerous reagents and expensive, high-pressure lab equipment.
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.
Of course, the FDA will require the LAL reagent to be used to test all of the vaccine batches that are produced, that's required for every vaccine right now.
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.
