Usage

General Description

Dipentyl oxalate is an organic compound with the chemical formula C15H26O4. It is a colorless, slightly viscous liquid that is commonly used as a plasticizer in the production of various polymers and resins. It is also used as a solvent in the manufacturing of adhesives, inks, and coatings. Dipentyl oxalate is known for its low volatility and high compatibility with a wide range of polymers, making it a versatile and effective plasticizer. It is considered to be a safer alternative to traditional phthalate-based plasticizers, as it does not pose the same health and environmental risks. Additionally, dipentyl oxalate is biodegradable and non-toxic, making it an environmentally friendly option for various industrial applications.

Method for synthesizing symmetric oxalate by using dimethyl oxalate and alcohols in one step

The invention relates to a method for synthesizing symmetric oxalate, in particular to a method for synthesizing the symmetric oxalate by using dimethyl oxalate and alcohols in one step. The symmetricoxalate is synthesized by using the dimethyl oxalate and the high carbon alcohols such as ethanol, propanol, butanol and pentanol as reaction raw materials and by adopting a one-step synthesis method. A catalyst used in the method is a mesoporous-microporous composite multifunctional basic catalyst, and has the advantages that mesopores significantly improve the mass transfer efficiency, while micropores significantly enlarge the specific surface area of a carrier and improve the dispersion of an active center. 10% MgO-5% Al2O3-8% Fe2O3/Na-meso-Y is used as the catalyst, the raw material ethanol and the dimethyl oxalate are enabled to be subjected to reaction under the atmospheric pressure at the temperature of 100 DEG C under the condition that the space velocity is 2 h-1, wherein the molar ratio of the raw material ethanol to the dimethyl oxalate is equal to 20 to 1; the selectivity of the product diethyl oxalate is stabilized to be about 82%, and the steady state operation is performed for 1000h; the catalytic activity and the product selectivity are basically unchanged. The whole reaction path has the characteristics of being short in synthetic route, simple in process flow and high in raw material conversion rate and product selectivity, and enabling the catalyst to be stable and non-deactivated.
