Formaldehyde is the main raw material for the manufacture of value-added chemicals such as melamine, urea-formaldehyde and phenolic resins.
The basic raw materials in PET, pure terephthalic acid (PTA) and monoethylene glycol (MEG), are chemically reacted with a small amount of co-monomers via a “polycondensation” process to form a base polymer. The resulting polymer is a polyester that is commonly used to make films and fibers.
Found in a brown bottle, hydrogen peroxide is an antiseptic liquid that in the past was typically used to treat cuts or other skin wounds, and kill germs. However, peroxide is often used in non-medical situations, including for cleaning, disinfecting and stain removal.
Sodium percarbonate is produced by the reaction of sodium carbonate with hydrogen peroxide, which can be done via dry, spray granulation and crystallization processes. In the dry process aqueous hydrogen peroxide solution is sprayed on solid sodium carbonate; a solid-liquid reaction yields sodium percarbonate.
Methyl methacrylate (MMA) is a type of organic compound and is used as a raw material monomer to manufacture mainly PMMA and acrylic resins. There are different production methods used to make MMA from materials such as acetone, isobutylene, and ethylene.
Syngas to MEG proceeds in two steps: the self-closing, green step of carbonylation of alkyl nitrile to produce dialkyl oxalate, and further hydrogenation of oxalate to MEG.
