Methyldiethanolamine MDEA(C5H13NO2) Colorless liquid
Methyldiethanolamine (MDEA) has found wide application in gas sweetening in the world in recent decades due to its many advantages over other conventional amines such as low energy required for reduction, selective separation ability, hydrogen sulfide in the presence of carbon dioxide and low corrosiveness. Hence, the major use of methyldiethanolamine in gas sweetening is in the refining and petrochemical industries.
MDEA is used in many industrial applications, including:
– Removal of acid gases from gas streams
– Natural gas purification and oil refining
– Production of various chemicals
– Pharmaceutical and health applications
Butylated hydroxytoluene BHT (C15H24O) White or light yellow powder
Butylated hydroxytoluene is a colorless, odorless, crystalline solid, insoluble in water and soluble in fats and nonpolar solvents. It is a derivative of phenol and is used as an antioxidant in the food industry by scavenging free radicals. Phytoplankton and green algae also produce butylhydroxytoluene.
BHT is widely used as an antioxidant in cosmetics, pharmaceuticals, rubber, electrical transformer oil, and winemaking fluids. It is also used as a food additive, industrial additive, pesticide, medicine, veterinary medicine, adhesive, ink and paint, rubber and plastic industries and as an additive in jet fuel.
Polyol Polyol Colorless, clear and viscous liquid
Polyurethane resins are polymers that typically have two or more hydroxyl groups in their molecular structure. The bulk of the raw material in the manufacture of polyurethanes is made up of polyols. The weight fraction of polyol used in the manufacture of polyurethane varies depending on its application, which leads to softness and flexibility in polyurethane, and in contrast, isocyanates and co-reactants cause polyurethanes to become hard and tough.
This commercial material, with a high molecular weight, is used in the manufacture of polymeric materials. Polyurethane is synthesized from the reaction of polyol with isocyanate. These materials can be used in the manufacture of mattresses, interior and exterior car parts, shoe soles, elastomers, thermal and acoustic insulation, coatings and sealants.
OrthodichlorobenzeneODCB (C₆H₄Cl₂) Colorless liquid
Orthodichlorobenzene is an aromatic isomer that is used as a solvent and intermediate in the pharmaceutical, agricultural, paint, foaming and nanotechnology industries. This compound is colorless, toxic and flammable and is miscible in organic solvents. The use of ODCB in the production process of isocyanates is of great importance due to its special chemical properties. The solvent properties and chemical properties of this compound have made it a key material in the production of isocyanates. Isocyanates are used as precursors in the production of a variety of important products such as polyurethane, flooring, insulation, and polyurethane foams.
