Isobutyl
What is Isobutyl acetate?
Isobutyl acetate is a liquid with a medium and colorless boiling point and a special fruity odor.
In many ways it is comparable to its normal type.
It is one of the ester solvents like normal bo teal, which is slightly faster in terms of volatility and has a lower viscosity than the normal type. Its volatility is not so fast that it leaves the paint film easily, nor is it slow enough to cause the film to weld Be colored and lead to problems with the color flow and thus reduce gloss.
Known as solvent in different colors due to its lower evaporation point than dry sooner. Normal type of varnish containing it Excellent solvent for nitrocellulose, cellulose acetate butyrate, celluloid, polyvinyl acetate, polyvinyl chloride, emollients, resins and paints.
Misobutyl acetate has very good solvent properties for resins, some polymers, alpha hydrocarbons, and is mainly used in the paint industry to make thinners and varnishes for wood and adhesives. As mentioned, economically suitable substitute for methyl isobutyl acetate (MIBK), normal butyl-acetate, is toluene in many formulations, if normal solvent evaporation is required, use normal butyl acetate instead. Turns. Its very good solvent properties cause the solvent to penetrate well into the film of the coatings and also helps to reduce their viscosity, due to the evaporation rate and suitable solvent properties, in coatings with a high percentage of solid as well as some inks. Printing is used.
Due to its electrostatic properties, it has advantages in the formulation of electrostatic sprays with high coverage and does not cause the problems that other solvents have in this type of coating. In the structure of some adhesives, this ester is also used. Some industries are used as extractors and can also be said to be used in the structure of some cosmetics.
Isobutyl acetate has three isomers:
1.Normal butyl acetate
2.Tertiary butyl acetate
3.Butyl acetate (methyl propyl acetate)
Because it has a lower viscosity than normal butyl acetate, it is used as a solvent for nitrocellulose varnishes, ethyl cellulose, natural gums and synthetic resins, which dilute them. Due to its lower evaporation point than normal butyl acetate, varnishes containing isobutyl acetate dry faster.
Since the amount of water in isobutyl acetate is low; Used as a solvent in reaction varnishes.
Suitable solvent in organic chemistry laboratories
Blurring of the layer does not occur with isobutyl acetate. The dilution power of isobutyl acetate is very good with common diluents such as aliphatic hydrocarbons such as ethanol and aromatic ones such as toluene.
In paint and resin industries and in various types of construction paints and industrial thinners
Used in a variety of varnishes, thinners, inks, plastic, glass, metal and wood coatings, synthetic leather, furniture, adhesives, photographic films of essential oil products, fruit flavors, perfumes, cosmetics and skin care products. Be.
Used as a solvent in the production of nail cleaners and other nail care products.
Isobutyl acetate is used as a color diluting agent in inks used to label fruits and vegetables.
It is a synthetic fruit flavor in food products such as candy, ice cream, baked goods, cheese, yogurt and so on.
It is also used in the pharmaceutical industry in the production of penicillin, which is a major component of many commercial compounds.
Isobutyl acetate is a flammable solvent, its flash temperature is ℃ 22 (the lowest temperature at which the liquid ignites) and it is therefore recommended that storage tanks of this solvent away from heat sources, direct sunlight and in the open or Maintain a well-ventilated closed environment. In the event of a fire, use an alcohol-free powder or foam and carbon dioxide capsule. Physical damage to the tanks containing this solvent should be prevented and fire extinguishing equipment should be installed next to these tanks.
In the event of a small amount of spillage or leakage on the ground, staff should wear appropriate clothing and remove heat sources from the scene of the accident, and clean the area of solvent as soon as possible, which can be used to absorb soil, because ISO Butyl acetate stays afloat, if it penetrates the aquatic environment it is likely to move to reach the source of the fire and cause a flame, which should prevent such incidents.
Major diffusion or leakage of this solvent occurs infrequently, but it is probable and arrangements should be made at its storage site. It is spread, collected, in the next steps, the collected solvent can be regenerated, but its disposal requires environmental considerations, firefighting equipment must be deployed at the same time, and firefighters must remove the sources of the fire from the site. Avoid the accident.
In the event of a fire to prevent unwarranted entry into the fire area, its hot vapors, because they are heavier than air, can travel long distances and with a mixture of air to reach anywhere they are likely to catch fire, even with Electrical charges are ignited. This should be anticipated and prevented, the use of direct water flow may cause the fire to spread. The use of foam and powder are suitable cases in case of fire of this solvent.
