The world market of solvents for paint and varnish materials is more than 15 million t\/year, of which 6.4 million t\/year is the share of hydrocarbon solvents. The main foreign companies producing solvents are: Dow Chemical, Eastman Chemical Co., Shell Chemical Co., Union Carbaid, AKSO. These are mainly large US companies with branches in Europe and other countries of the world that produce a well-known range of solvents for the paint industry.<\/p>\n
The global solvent market capacity should reach $33 billion by 2019. Their consumption increases by approximately 2.5% per year. This indicator exceeds the growth rate of the world economy. The most commonly used solvents are alcohols such as ethanol, n-butanol, isopropanol and methanol. The demand for solvents for the automotive industry will depend on the popularity of coolants and antifreezes.<\/p>\n
Organic solvents for LFM are losing popularity in Europe and North America. However, they are widely used for the production of paints, coatings and adhesives throughout the rest of the world. The dynamic development of the economy in countries such as China, India, and Brazil will contribute to the growth of demand for solvents. Currently, about 39% of global consumption is in the Asia-Pacific region.<\/p>\n
Petroleum solvents with different contents of aromatic components belonging to the class of gasoline, only crude oil, kerosene are produced by Exxon Chemical (USA) under the brand name Solvesso and Shell Chemical Co. (Netherlands) under the brand Shell Cyclosol.<\/p>\n
The approval of stricter requirements for environmental protection led to the development and development of new, less toxic, types of solvents.<\/p>\n
Dow Chemical has developed a series of low-toxic solvents based on propylene glycol (dipropylene glycol and tripropylene glycol) under the Dowanol P brand. These solvents are used in LFM with a high dry residue and in water-dispersion paints.<\/p>\n
An urgent issue is the reduction of the emission level of volatile organic solvents (VOCs) into the environment. For this purpose, the company unijn Carbide manufactures EER solvents, butyl and pentylpropionate ethers of the Ucar brand to replace traditional esters (for example, butyl acetate).<\/p>\n
The replacement of chlorinated hydrocarbons is especially important. For this purpose, Chemoxy International developed Extasol and Coasol solvents. They are a mixture of refined dimethyl n diisobutyl ethers of adipic, glutaric and succinic acids. When introducing these solvents instead of acetone, the level of VOC emission decreases by 90% in the case of Coasol, Extasol – by 80%. They have a high flash point – over 100 \u00b0 C and are practically safe for storage. Effective when used in washes.<\/p>\n
The Occidental Chemical company has developed the n-chlorobenzotrifluoride Oxsol-100 solvent, which does not have photochemical activity and does not pollute the atmosphere.<\/p>\n
In the USA, oxoacetates produced under the brand name Exxate (Exxate 600 and Exxate 700) have become widespread. They are hexyl and heptyl acetate solvents that have reduced toxicity and successfully replace acetone and acetate solvents that improve the gloss, impact resistance of coatings and the ability to apply in electrostatic field. Increase the duration of storage of polyurethane materials cured by moist air.<\/p>\n
The Shell company has mastered the production of simple esters of glycols of the Oxitol, Proxitol, and Dioxitol brands. Such solvents are widely known in the industry due to the combination of the following properties:<\/p>\n
1) high dissolving power;<\/p>\n
2) excellent miscibility with both water and hydrocarbon solvents<\/p>\n
3) relatively low volatility;<\/p>\n
4) good compatibility with various solvents.<\/p>\n
Due to the high polarity of Oxitols and Proxitols, their mixtures with white spirit can replace mixed solvents of multicomponent composition (%), for example, a mixture of: n-Butyl Oxitol (46%), white spirit (54%) replaces the following composition of solvents ( %): acetone (8), MEK (2), propanol-2 (15), n-6-ethyl acetate (10), toluene (65).<\/p>\n
