Usage

General Description

Dioctyl benzene-1,3-dicarboxylate, also known as dioctyl terephthalate (DOTP), is a synthetic organic compound commonly used as a plasticizer in many industrial applications, including the production of PVC plastics, vinyl flooring, and cables. It is a clear, colorless liquid with a mild, sweet odor, and is highly stable and resistant to heat, light, and moisture, making it a popular choice for enhancing the flexibility and durability of plastic products. Additionally, DOTP is considered to be a safer alternative to traditional phthalate plasticizers due to its low toxicity and minimal impact on human health and the environment. Overall, dioctyl benzene-1,3-dicarboxylate is an important chemical in the manufacturing of various plastic products, providing essential properties for their performance and longevity.

Mucor miehei lipase catalyzed transesterifications on aromatic and heteroaromatic substrates. A general survey

An investigation on Mucor miehei lipase-catalyzed transesterifications of 16 aromatic and heteroaromatic esters in organic solvents is described. The points studied were the activity and regioselectivity of the enzyme-catalyzed reaction of either one or two ester groups situated in different positions on several heterocyclic systems with an aliphatic alcohol. The reactions took place in moderate to good yields and, in some cases, regioselectively.
