Normally, it can be expressed with a chemical formula. For an example, the chemical formula for water is H2O, thus the chemical composition of water may be interpreted as a 2:1 ratio of hydrogen atoms to oxygen atoms. For a mixture, the chemical is equivalent to quantifying the ...
for a polymer or copolymer comprising monomers of formula (II), at least one of these monomers comprises at least one of the groups R1to R4which bears said group capable of reacting with the chemical compound to be detected and which is not involved in radical polymerization. Alternatively, th...
Lithium hexafluorophosphate(picture 1) is an inorganic substance with the chemical formula LiPF6, white crystal or powder[1]. Easily soluble in water, but also soluble in organic solvents such as low-concentration methanol, ethanol, acetone, carbonates, etc. It is the most important part of...
This catalyst is suitable for the synthesis of cyclic carbonates from epoxides and CO2 with TBAB catalyst under a no solvent or mild reaction. Its treatment activity on postoperative bacterial infection was also determined, and bacterial survival was calculated. Relative ftsZ expression in bacteria was...
For esters, see Carbonic acid, esters. 这条著录说明,Carbonates 在GS 中是CAS确定的索引主题;要查碱金属碳酸盐方面的文献,应该到CS中在Carbonic acid, compounds 这个索引主题下去查。根据这个说明在v.114(p191192u)查到了有关文献。因此当查阅过程受阻时,不妨变换一下思路。 * * vjghkjh (二)关键词索引 ...
The formula of this organic compound is CH3COOH. achromatic (chem.) An achromatic lens is used when color abberation needs to be avoided. acicular (chem.) The MSDS (material safety data sheet) describes wollastonite as an acicular material. acid (chem.) A superacid is an acid that has a ...
Acetic acid is an organic compound with the formula CH3COOH. It is a carboxylic acid consisting of a methyl group that is attached to a carboxyl functional group. The systematic IUPAC name of acetic acid is ethanoic acid and itschemical formulacan also be written as C2H4O2.Vinegar is a solut...
Alkaline earth metals produce ionic hydrides (originally called hydrogenides) with the general formula MH₂ (where the symbol M stands for an alkaline earth metal). Beyond the formation of these hydrides, they are also molecular solids, having a high melting and boiling point, due to the stre...
A suitable method of preparation is to impregnate a support with solutions of the desired metals. Suitable compounds useful for impregnation include the acetates, acetylacetonates, oxides, carbides, carbonates, hydroxides, formates, oxalates, nitrates, phosphates, sulfates, sulfides, tartrates, fluorides...
