Structure and expression of benzene (1) the structure of modern physical methods proved benzene: Benzene six carbon atoms and six hydrogen atoms are in the same plane of propylene glycol monomethyl ether manufacturers, so it is a flat molecule, composed of six carbon atoms A regular hexagon glycol methyl ether, carbon-carbon bond length is equal about 140 pm methoxypropylacetate offer, ranging between single and double bonds. Hydrocarbon bond length of 108pm, all the bond angles are 120 °. Physical properties edit aromatic hydrocarbon insoluble in water, but soluble in an organic solvent propylene glycol methyl ether market, such as diethyl ether, carbon tetrachloride, petroleum ether and other non-polar solvents. Generally lighter hydrocarbons than water; boiling point with the relative molecular mass temperature increased; melting point except with the relative molecular mass of related, but also related to its structure, usually para isomers due to molecular symmetry, low melting point. Physical properties of some common aromatics are listed in the following table: Shandong Zaozhuang propylene glycol methyl ether ether _ _ Xiang Xiang dry dry chemical from Jinan Chemical Limited.
