Toluene

Toluene

Toluene is found naturally in crude oil, and is used in oil refining and the manufacturing of paints, lacquers, explosives (TNT) and glues. In homes, toluene may be found in paint thinners, paintbrush cleaners, nail polish, glues, inks and stain removers. 

Application:

  • Paints
  • Paint thinners
  • Fingernail polish
  • Lacquers
  • Adhesives and rubber and in some printing 
  • Leather tanning processes

 

Toluene

 

Toluene, a flammable liquid with a pungent odor, is widely employed as an organic solvent. It is also used as a precursor for synthesizing benzene.

Methanol

Methanol

Methanol is a nondrinking type of alcohol (also known as wood alcohol and methyl alcohol) which is mostly used to create fuel, solvents and antifreeze. A colorless liquid, it is volatile, flammable, and unlike ethanol, poisonous for human consumption. Methanol is also used to produce a variety of other chemicals, including acetic acid.

Small amounts of methanol occur naturally in many living organisms as part of their metabolic processes. For example, methanol occurs naturally in many fruits and vegetables.

Application:

  • Antirfreeze 
  • Solvent
  • Fuel

Methanol

Antifreeze

Methanol has chemical properties which allow it to lower the freezing point of a water-based liquid and increase its boiling point. These attributes lead methanol to be used as an antifreeze in windshield washer fluid to keep the cleaning fluid from freezing. It is also injected in natural gas pipelines, where it lowers the freezing point of water during oil and gas transport.

Solvent

Methanol is primarily used as an industrial solvent to help create inks, resins, adhesives, and dyes. It is also used as a solvent in the manufacture of important pharmaceutical ingredients and products such as cholesterol, streptomycin, vitamins and hormones.

Fuel

Roughly 45 percent of the world’s methanol is used in energy-related applications. Methanol can be used as a type of vehicle fuel or marine fuel for boats. It can also be blended into gasoline to produce an efficient fuel known as methyl tertiary butyl ether (MTBE) which can have lower emissions than conventional gasoline. Methanol also is used in biodiesel, a renewable type of fuel made from plants or animal fats that can be used in place of, or blended into, conventional fuel.

Benzene

Benzene

Benzene is a widely used industrial chemical. Benzene is found in crude oil and is a major part of gasoline. It's used to make plastics, resins, synthetic fibers, rubber lubricants, dyes, detergents, drugs and pesticides. Benzene is produced naturally by volcanoes and forest fires.

In homes, benzene may be found in glues, adhesives, cleaning products, paint strippers, tobacco smoke and gasoline. Most benzene in the environment comes from our use of petroleum products.

Benzene quickly evaporates from water or soil. If benzene leaks from buried storage tanks or landfills, it can contaminate nearby drinking water wells. Benzene can move long distances in groundwater.

Application:

  • Plastics
  • Resins
  • Synthetic fibers
  • Rubber lubricants
  • Dyes
  • Detergents
  • Drugs 
  • Pesticides

Benzene

The most common way people are exposed to benzene is when they fill their car with gasoline. People are also exposed to benzene when they use household products that contain benzene.

Benzene evaporates quickly from contaminated water. People can be exposed to benzene if they use contaminated water to bathe, shower, wash dishes or do laundry.

Mixed Xylene

Mixed Xylene

Mixed Xylene is a colourless, flammable aromatic hydrocarbon liquid with a sweet odour. It is a mixture of different isomers of xylene such as meta-xylene, para-xylene, ortho-xylene and ethylbenzene.

Mixed Xylene is used as a solvent in many industries, such as paints and coatings, pesticides, printing, rubber & leather, etc. It can be used in place of toluene where slower drying process is desired. Mixed Xylene is a widely used solvent and is considered to be fit to be used as a solvent in paints, pesticides and other products due to its better adhesive properties.

Application:

  • Solvent
  • Paints and coatings
  • Pesticides
  • Printing
  • Rubber 
  • Leather

Mixed Xylene

 

The paints & coating market is continuously growing owing to increasing demand from automotive and construction industries. Additionally, growing demand for solvent grade mixed xylene from printing, rubber & leather industries will also give a push to the mixed xylene market over the forecast period.

The Solvent Grade Mixed Xylene segment is expected to grow at 6.5% CAGR, by value, during the forecast period. Growing demand for a better solvent material in different industries is projected to create new opportunities for mixed xylene to grow in the market.
