What is the business of Thirumalai Chemicals?

Thirumalai Chemicals manufactures and sells organic chemicals in India. It ranks among the largest producers in the world of phthalic anhydride, malic acid, maleic anhydride and fumaric acid.

What is maleic anhydride commercial use?

Around 50% of world maleic anhydride output is used in the manufacture of unsaturated polyester resins (UPR). Chopped glass fibers are added to UPR to produce fiberglass reinforced plastics that are used in a wide range of applications such as pleasure boats, bathroom fixtures, automobiles, tanks and pipes.

Where is malic acid manufactured?

Malic acid was first described by Sheele who, in 1785, isolated this acid from unripe apples. The name malic is from the Latin for apple, malum. Malic acid is found in other fruits such as grapes, watermelons, cherries, and in vegetables such as carrots and broccoli.

Where is fumaric acid found?

Natural sources of fumaric acid include bolete mushrooms, lichen, and Iceland moss. It’s also found in papayas, pears and plums, but in very limited amounts. It was first isolated from the plant Fumaria officinalis, which is where it derives its name.

What are the risks of maleic anhydride?

Chronic (long-term) exposure to maleic anhydride has been observed to cause chronic bronchitis, asthma-like attacks, and upper respiratory tract and eye irritation in workers. In some people, allergies have developed so that lower concentrations can no longer be tolerated.

What is SMA plastic?

Styrene maleic anhydride (SMA) is known as a polymer that enhances heat deflection of polymers like PVC that are amorphous. SMA can also be used as compatibilizer in amorphous thermoplastics and copolymers to improve thermal performance, surface polarity and miscibility with other resins in blends and alloys.

Is malic acid organic?

Malic acid is an organic compound with the molecular formula C 4H 6O 5. It is a dicarboxylic acid that is made by all living organisms, contributes to the sour taste of fruits, and is used as a food additive.

What is the pH of malic acid?

2.2. Malic acid is a diprotic acid, whose pKa at 25°C are 3.40 and 5.11 (Lide, 2005). Due to these values, at a pH of 3.50, the undissociated form (H2M) accounts for approximately 47% of the total concentration, while the dissociation of the first carboxylic group (HM−) represents the 51.7% (Usseglio-Tomasset, 1985).

Can you eat fumaric acid?

Is Fumaric Acid Safe to eat? Yes, its safety when used as a food additive has been approved by the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), Joint FAO/WHO Expert Committee on Food Additives (JECFA), as well as other authorities.
