Glycerin is commonly called glycerol or glycerin. Glycerin is a sweet-tasting alcohol, which is colorless and odorless. It becomes a gummy paste when frozen, although freezing it can only be achieved at very low temperatures. It melts at 18 degrees Celsius and boils at 290 degrees Celsius. Its chemical formula is C3H8O3. It is miscible in water and alcohol. However, it does not mix with oil. It is an excellent solvent. In fact, there are substances that dissolve better in glycerol than in water or alcohol.

The compound absorbs water from the air. This is why it is known as a hygroscopic substance. Suppose you leave a container of pure glycerin or glycerol in open air, it will become diluted as it attracts water molecules. According to a speculation, a drop of this liquid in the tongue can raise a blister because it would draw out water from deep into the tongue tissue. But this remains a clever speculation.

The sweet-tasting alcohol is found in many skin moisturizing lotions and creams because of the water-retaining and water-absorbing capacity. Thus, it softens and smoothens the skin. It is believed, however, that this substance has other beneficial properties aside from simply moisturizing and attracting water molecules.

The compound originates from fats and oils. In fact, molecules of fat contain glycerol. One way to extract it from fats or oils is through saponification - a chemical reaction involving a fat and an alkali. This chemical reaction produces soap. Soap-making is a common source of this trihydric alcohol under discussion.

Methyl Isobutyl Ketone (MIBK) is an organic compound with the formula. (CH3)2CHCH2C(O)CH3. Our clear and colorless Methyl Isobutyl Ketone (MIBK) is widely used as a solvent. Methyl Isobutyl Ketone (MIBK) is stable and does not polymerize and is highly compatible with a variety of organic reagents and is a bood solvent for a wide range of industrial material. MIBK contains dewaxing and separating properties that can be used in the purification of pharmaceuticals, mineral oils, tall oil, stearic acid, and butanol. Methyl Isobutyl Ketone (MIBK) is very flammable with a high vapor pressure, use only with good ventilation and avoid all ignitition sources.

Applications :

• Used as a chemical intermediate, a solvent for manufacturing paints, rubbers, pharmaceuticals, other chemicals, and industrial cleaners
• It is used in the semiconductor industry
• It is very efficient at dissolving resins used in paints, inks, lacquers, and other types of surface coatings
• Is a Food and Drug administration (FDA)- approved indirect food additive for adhesives, paper and paperboard and planers
• Due to its quite low solubility in water, it is useful for liquid-liquid extraction
• It has a similar polarity to ethyl acetate, but greater stability towards aqueous acid and base. It can be used to extract gold, silver and other precious metals from cyanide solutions, such as those found at gold mines, to determine the levels of those dissolved metals
• Used as a denaturing agent for denatured alcohol. When mixed with water or isopropyl alcohol MIBK serves as a developer for PMMA electron beam lithography resist
