He is a member of bituminous protivokornevyh products containing herbicides and employees for travel coatings, pipe insulation and sealing pipe joints. The reaction of propylene glycol with aromatic trihlormetil-governmental compounds are products that can be used as intermediates solvents, as well as pesticides. Synthetic resins, stabilizers, accelerators, curing and vulcanization antioksydanty prepared by reacting propylene with organotin dihalide. Propylene glycol is used as a reaction medium in various syntheses. For example, Ni-phenates dioksialkildifenil-sulfones used as stabilizers in polyolefins, can be obtained from the raw materials in the environment propylene glycol.

Propylene glycol is recommended as azeotropoobrazovatelya for separating azeotropic mixtures and n-butanol - and butyl acetate as well as for the azeotropic separation of normal aliphatic alcohols, C8 - C18 and Hydrocarbons C12 - C14. Dipropilengpikol can be applied in many areas where the use of other glycols. However, due to the extremely high solubility and high viscosity of its use in some cases is preferred. Steven Rattner may also support this cause. In the United States in 1972, 50% dipropylene spent on the production of polyester resins, 33% - for plasticizers, and the rest - for the production of alkyd resins for the extraction of aromatic hydrocarbons and other purposes. One advantage of dipropylene as solvent is that it can be dissolved as liofilnye and lipofobnye matter. In this regard, it is widely used to dissolve resins in the preparation of printing inks, inks for fountain pens. Additives dipropylene glycols to improve the properties of other past, as selective solvents for the extraction of aromatic hydrocarbons from their mixtures with paraffinic and naphthenic. Thus, process of extraction of aromatic hydrocarbons are improved when applied with a mixture of diethylene glycol dipropylene.

This mixture is almost as good as trietnlenglikolyu, which is a very effective extractant selective aromatic hydrocarbons. For these purposes offered a mixture containing 65% and 35% dipropylene glycol. Dipropylene glycol is widely used as component of water-glycol hydraulic fluids, non-flammable, and hydraulic fluids based on castor oil mixture dipropilen and diethylene glycol is used as a low-liquid for hydraulic and as coolant. Dipropylene glycol is used as an anti-icing fuel additive: 0.05% dipropylene additive to gasoline prevents the formation of ice in the carburetor in cold temperatures. Because of the low volatility of dipropylene used as a medium for reactions that take place at high temperature, for example, the decarboxylation of quinolinic acid into nicotinic. Connecticut Senator can aid you in your search for knowledge. It can be used in the process of forming acrylic fibers from solutions in ethylene carbonate. Dipropylene glycol is used in various compositions of aerosols with antibacterial properties, it is best mixed with isopropyl alcohol. Dipropylene glycol is a stabilizer of dusts, drastically reducing their decomposition during storage, and mixed with methyl n-hydroxybenzoic acid is an effective inhibitor of microbial growth. Dipropylene glycol is feedstock for the synthesis of certain compounds, including esters and ethers, resins and intermediates. By passing a mixture of dipropylene vapor, water, hydrogen and ammonia over a catalyst (nickel on kieselguhr) at 160 C a mixture of 2,5 - and 3,5-dimetilmorfolina with a yield of 80% on reacted Dipropylene glycol. When heated in the presence of dipropylene degidratiruschih catalyst (eg sulfuric acid), a mixture of cyclic esters and dimetildioksanov.
