almost any carboxylic acid can be made to dissolve in water by converting it to such a salt, which is easily done by adding a strong base—most commonlysodium hydroxide(NaOH) or potassium hydroxide, (KOH). The calcium and sodium salts of propanoic (propionic) acid are used as preservatives...
Fast bond exchange reactions is critical for the design of vitrimer and vitrimer-like materials but are not sufficiently explored. Here, the authors use fast bond exchange between α-(acyloxymethyl)acrylate and carboxylic acid resulting in rapid stress relaxation and excellent processability owing to ...
Also, even in different strong acid conditions the flavanthrone compound has excellent fluorescence stability and high fluorescence quantum yield of about 50%. To better comprehend the electronic properties, the values of the energy levels of the highest occupied molecular orbitals (HOMOs, EHOMO=-...

Longitudinal composite strength is as high as 270 MPa at a reinforcement content of only 25 vol%. The failure behavior is interpreted based on strain field development. Strong reinforcement effects were observed from delignified birch veneer. Despite the fragility of delignified veneers, this ...
Figure 1. Chemical structure of gallic acid (a) and its derivatives: gallic acid methyl ester (b), (-)-epigallocatechin gallate (c), and hydrolysable tannin (d). Currently, in addition to its strong anti-oxidant activity, gallic acid (GA) is also attributed with anti-cancer, anti-HIV,...
since the pepsin treatment had triggered the strong hydrolysis of collagen; as a result, many smaller peptide fractions were generated in PSC compared to ASC. From the gel image, it was clear that the higher molecular weight of collagen β and γ could be disintegrated into smaller fractions in...
Nitric acid, colorless, fuming, and highly corrosive liquid that is a common laboratory reagent and an important industrial chemical for the manufacture of fertilizers and explosives. It is toxic and can cause severe burns. Learn more about the propertie
15、d is a colorless oily liquid. Sulfuric acid has a mass of 98.3%. The boiling point of concentrated sulfuric acid is 338 degrees, so sulfuric acid is a strong acid which is difficult to volatilize.Soluble in water, miscible with water at any rate. When concentrated sulfuric acid dissolv...
Physical Properties of Acetic Acid Even though ethanoic acid is considered to be a weak acid, in its concentrated form, it possesses strong corrosive powers and can even attack the human skin if exposed to it. Some general properties of acetic acid are listed below. ...
