Modelling and optimisation of an industrial batch process
Dioctyl phthalate (DOP) is used in substantial quantities in industry, primarily as a plasticiser for PVC and other polymers. One route to its production is via the esterification of 2-ethylhexanol (2EH) with phthalic anhydride (PA) using a homogeneous catalyst. The process can be carried out in batch reactors.
Bis(2-ethylhexyl) phthalate
Bis (2-ethylhexyl) phthalate ( di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers. It is the diester of phthalic acid
DOP Plant - Cey Kimya
DOP Production: We are building turn-key DOP plant and as you can see on our website, companies that have been producing DOP for the past 40-50 years get consultancies from us to produce higher quality product with less energy and less losses (DOP mud). WHY they are receiving counseling from us? As you know, technology is constantly evolving.
CN102295564A - Continuous production process for DOP (Dioctyl
The invention relates to a continuous production process for DOP (Dioctyl Phthalate) and used equipment, which belong to the technical field of fine chemical production. The continuous production process comprises the following steps of: firstly carrying out esterification reaction of phthalic anhydride and isooctyl alcohol in the presence of a
- What is dioctyl phthalate (DOP)?
- Dioctyl phthalate (DOP) is used in substantial quantities in industry, primarily as a plasticiser for PVC and other polymers. One route to its production is via the esterification of 2-ethylhexanol (2EH) with phthalic anhydride (PA) using a homogeneous catalyst. The process can be carried out in batch reactors.
- 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 is dioctyl phthalate made?
- II.Reaction Principle DOP is manufactured by the esterification reaction between phthalic anhydride and octanol to produce dioctyl phthalate and water. III. Process Flow
- How to make phthalic anhydride octanol esterification reaction?
- Process Flow 1. Add phthalic anhydride and octanol into the reaction kettle according to a certain ratio, heat up to a certain temperature, and start the esterification reaction. 2. During the reaction, catalyst needs to be added in time to promote the reaction.
- Can phthalates be produced at high temperature without a catalyst?
- It has been stated in the literature that phthalates were produced at high temperature in the absence of catalyst or by esterification of phthalic anhydride with n-octanol in the presence of catalyst (Ishikawa et al., 1997).
- What raw materials are needed for the manufacture of DOP?
- The following raw materials are needed for the manufacture of DOP: phthalic anhydride, octanol. II.Reaction Principle DOP is manufactured by the esterification reaction between phthalic anhydride and octanol to produce dioctyl phthalate and water. III.
