4) Synthesis of chemical and petrochemical industries common acids and bases as catalyst for esterification, hydrolysis, transesterification, hydration and other reactions in organic synthesis. Ion exchange resins instead of inorganic acids, bases glycol, the same above reaction can be carried out, and the advantages more. The resin can be used repeatedly, the product is easy to separate the reactor will not be corroded glycol price quotes, do not pollute the environment, and the reaction is easy to control. Preparation of methyl tert-butyl ether (MTBE), is to use macroporous ion exchange resin as a catalyst, the reaction of isobutene with methanol made, instead of the original can cause serious pollution to the environment tetraethyl lead. 5) Environmental ion exchange resin has been applied on many environmental issues of great concern. At present, contains many toxic aqueous or non-aqueous ionic or non-ionic substances, these resins can be used for recycling use. Such as the removal of metal ions from electroplating wastewater, waste recycling filmmakers and other useful substances in the description of molecular structure, specific to the molecule of a substance, we should say: Each molecule is composed of a certain number of atoms. Emphasize a molecule! The compound represented by the chemical symbol of each element in atomic proportions formula called an empirical formula, such as acetylene and benzene are hydrocarbons, which are carbon-containing composition was 92.3%, hydrogen 7.7%, the ratio of carbon and hydrogen atoms is 1:1, empirical formula derived acetylene and benzene are CH. Some inorganic compounds (eg sodium chloride) is composed of ionic crystals, the crystal of cations and anions are arranged alternately. However, sodium chloride crystals in the end the number of sodium ions and chloride ions unresolved, only know Na:Cl = 1:1 glycol condensing agent, it can only be used on behalf of the empirical formula of sodium chloride NaCl. Chemical symbol indicates that the substance of the chemical formula consisting of molecules called Formula wholesale high quality ethylene glycol, its meaning is: the elemental composition of the compound; ratio of the number of atoms of each element; the weight of the atoms of each element and. Chemical symbols and valence bond between the atoms in the compound represented by way of chemical structure called structural formula, it points out the order and connection of the atoms in the molecule, an organic compound commonly used in structural formula, it can eliminate the same phenomenon caused due to the heterogeneous disadvantage of the different compounds represented by the formula. Such as n-butane and isobutane formula is C4H10, but different Cheung dry chemical structural formula (Figure) | Shandong glycol | Shanxi glycol provided by Jinan Cheung Chemical Co. dry.
