- What is the manufacturing method of dioctyl phthalate (DOP)?
- Manufacturing method of dioctyl phthalate (DOP) Dioctyl phthalate (DOP) is a common plasticizer widely used in plastics, rubber, paints, coatings and other fields. This article will introduce the manufacturing method of DOP. I. Raw material preparation The following raw materials are needed for the manufacture of DOP: phthalic anhydride, octanol.
- How to synthesize dioctyl phthalate?
- Dioctyl phthalate were synthesized by using acid functionalized ionic liquid as catalyst. The results indicated that HSO 3 -functionalized Brønsted acidic ionic liquids show better catalytic and reusable performance than non-functionalized ionic liquids or the combination of neutral ionic liquids and Brønsted acid.
- What is dioctyl phthalate (DOP)?
- The object of the invention is to overcome the deficiencies in the prior art, a kind of preparation method of dioctyl phthalate (DOP) is provided, to simplify technique, economize in raw materials, strengthen environmental protection, make the purity of product disposablely to reach requirement becomes possibility simultaneously.
- Which ionic liquid is best for synthesis of dioctyl phthalate?
- For the synthesis of dioctyl phthalate, HSO 3 – functionalized Brønsted acidic ionic liquids show better catalytic and reuse performances than the non-functionalized ionic liquids and the combination of neutral ionic liquids and Brønsted acid. Therefore, an environmental friendly approach for the synthesis of dioctyl phthalate is provided.
- How many times can dioctyl phthalate be reused?
- After easily separated from the products the ionic liquid could be reused 8 times without any disposal, and the conversion of phthalic anhydride was not less than 95%. Therefore, an environmental friendly approach for the synthesis of dioctyl phthalate is provided. 1. Introduction Dioctyl phthalate (DOP) is a kind of widely used plasticizer.
- How to make phthalic anhydride octanol esterification reaction?
