Methyl Tert-Butyl Ether is an organic compound with the chemical formula C5H12O and is a saturated aliphatic ether family. At standard temperature and pressure, it is a colorless, flammable liquid with a molecular weight of 88.15. This composition has a melting point of -9°C, a boiling point of 55.2-53°C and a vapor pressure of 0.268 bar at 20°C. MTBE is colorless, flammable, soluble in water, and volatile at room temperature. Compounds containing oxygen act as an increaser of the octane number of gasoline and have the advantage of making the combustion of gasoline more complete, significantly reducing the pollutants emitted from the exhaust of cars. In some cases, it has medical use as a gallstone dissolver. Advantages of using MTBE: significant reduction of its risks on human health and smog-forming pollutants, its advisability compared to tetraethyl lead and other additives, having a high octane number compared to other oxygenated substances, ease of obtaining raw materials for its production, appropriate vapor pressure and boiling point, reasonable cost of production, no corrosion or effect on metals (Raffinate II) as a side product (with a production of 60 thousand tons per year)

Butane fraction or C4 Raffinate II is a mixture of C4 hydrocarbon compounds, which is classified as a liquefied gas group. These gases are liquid under a certain pressure and temperature (e.g., in production conditions in the MTBE unit), they turn into steam at the normal environment temperature and pressure. These gases are heavier than air and their vapors are combustible. This substance is a combination of four carbon gases including butene (cis, trans 2-butene, and 1-butene) and butane (isobutane and normal butane). It is used in the production of olefinic units besides the raw materials. It is also used in the production of MEK and as fuel. The ignition temperature is -80°C to -60°C (according to DIN 51755 standard). The ignition temperature is 324°C to 465°C (according to DIN 51755). Density at 25°C is 580 kg/m3, and vapor pressure is 1.918 bar at 20°C

This material is widely used in refineries to produce engine base oil, paint, and resin industries, printing and synthetic leather as an important commercial industrial solvent. It is used as solvent for paint, thinner and vinyl, nitrocellulose, acrylic, epoxy, and urethane resins, solvent for the waxing process in motor base oil production refineries, solvent for the production process of base adhesives, solvent for varnishes and printing inks, solvent for polyurethane in synthetic leather industries, degreasing solvent for metal surfaces, and solvent for urethane varnishes to prepare the cover of magnetic strips

Most of the production of Sec-Butanol (SBA) is used to produce Methyl Ethyl Ketone (MEK). Butanol is also used in the production of Sec-Butyl Acetate and pharmaceutical intermediates. In addition, it is used as a solvent in paints, coatings, resins, and adhesives. Especially its mixture with aromatic hydrocarbons is a very suitable solvent for alkyd resins and ethyl cellulose varnishes. Since SBA is able to dissolve both water and some oils, it is used in the process of making brake oils and cleaners. Furthermore, SBA is used in the process of preparing perfumes, colors, fruit essences, and moisturizers

It is a byproduct of the company's production process. As a pressurized gas, this product is rich in C4 butane, being suitable for use in chemical and thermal industries

Heavy alcohol is created as a byproduct in the MEK production process. It contains a mixture of heavy linear alcohols and heavy hydrocarbons, being used in fuel applications
