Cyclohexane
Cyclohexane (English name: Cyclohexane) is a colorless liquid with a gasoline odor. It is insoluble in water and can be miscible with various organic solvents such as ethanol, ether, acetone, benzene, etc. The solubility in methanol is 57 parts of cyclohexane for 100 parts of methanol (25°C). It is volatile and flammable, with a flash point of 18°C. The vapor forms an explosive mixture with air, and the explosion limit is 1.3-8.3% (volume). It is relatively stable to acids and alkalis. It doe...Read more -
Heptane
There are nine isomers of n-heptane, among which n-heptane [CH3(CH2)5CH3] is the most important. It is a colorless flammable liquid. It is almost insoluble in water, slightly soluble in alcohol, and soluble in ether and chloroform. Its vapor forms an explosive mixture with air, with an explosion limit of 1.0Chemicalbook~6.0% (volume). It is separated from petroleum fractions. It vibrates violently when it burns and explodes in the cylinder. Its octane number is set as zero. Mixtures of variou...Read more -
Propionic anhydride
Properties: Due to the presence of oxygen atoms in its molecular structure, propionic anhydride has a stronger electronegativity than propionic acid and is easier to react chemically. It is an active organic chemical intermediate and has important applications in the field of fine chemicals. Application: Propionic anhydride is widely used in the fields of pesticides and medicines. It is an important organic synthetic raw material, especially in pesticides. It mainly supplies the production ne...Read more -
Acetic anhydride
Acetic anhydride (chemical formula: (CH3CO)2O) is the simplest isolable anhydride of a carboxylic acid, is widely used as a reagent in organic synthesis. It has an internal asymmetric structure, leading to its potent electrophilicity. In organic chemistry, it is mainly used in acetylation for the manufacture of commercially significant materials, e.g. it can be used for the conversion of cellulose to cellulose acetate and aspirin. It can also be used as a wood preservative. In starch industry...Read more -
