What is the use of dioctyl phthalate?

Dioctyl Phthalate (DOP) is a general use Plasticizer. As a PVC plasticizer, DOP is used in formualtions of screen printing inks. Known for its good stability to heat and ultraviolet light, DOP can be used in applications such as paints, lacquers, inks, adhesives, and sealants.

How do you make dioctyl phthalate?

Dioctyl phthalate (DOP), an industrial plasticizer is prepared by treating 2-ethyl hexanol with phthalic anhydride in the liquid phase either with a monoester intermediate stage or by a direct routel. For esterification of phthalic anhydride with 2-ethyl hexanol, normally, sulphuric acid is used.

What is dioctyl phthalate plasticizer?

Dioctyl Phthalate (DOP) is a plasticizer used in the production of flexible polyvinyl chloride (PVC) plastic. Dioctyl Phthalate is one of the most widely used plasticizers in PVC due to its low cost.

How do you make phthalates?

Phthalates are the esters of 1,2-dibenzene dicarboxylic acid; their general structure is given in Figure 1. They are produced by the addition of an excess of branched or normal alcohols to phthalic anhydride in the presence of a catalyst.

Is DOP a plasticizer?

It is the most widely used all-purpose plasticizer offered by Eastman™ for use with polyvinyl chloride (PVC) resins. It is insoluble in water and has a viscosity of 56 cP at 25°C. Eastman™ DOP features good stability to heat and ultraviolet light, a broad range of compatibility, and excellent resistance to hydrolysis.

Is DOP flammable?

Fire Hazards in Presence of Various Substances: Slightly flammable to flammable in presence of open flames and sparks, of heat. Non- Page 3 MSDS – Dioctyl phthalate Page 3 of 7 flammable in presence of shocks.

Is 2 ethylhexyl phthalate DEHP?

1.1 WHAT IS DEHP? DEHP, which is an abbreviation for di(2- ethylhexyl) phthalate, is a manufactured chemical that is commonly added to plastics to make them flexible. Other names for this compound are dioctyl phthalate (DOP) and bis(2-ethylhexyl) phthalate (BEHP).

What is another name for phthalates?

Is bis 2 ethylhexyl phthalate harmful?

DEHP is on the Proposition 65 list because it can cause cancer and birth defects or other reproductive harm. Exposure to DEHP may increase the risk of cancer, and may also harm the male reproductive system. Exposure to DEHP during pregnancy may affect the development of the child.

What is dioctyl phthalate (DOP)?

Dioctyl phthalate is used in the production of synthetic rubber. Dioctyl phthalate is used as a softening agent to make the synthetic rubber easier to rebound and harder to undergo form change under pressure. DOP is used to increase the performance properties of wood coating formulations.

How do you make dioctyl phthalate from phthalic anhydride?

Dioctyl phthalate is produced by the esterification of phthalic anhydride with 2-ethylhexyl alcohol using a homogeneous acid catalyst such as concentrated sulfuric acid. The process can be performed in batch reactors with controlled condition of temperature for 16-20 hours.

What is the compatibility limit of dioctyl phthalate with poly (ethylene oxide)?

It is known that compatibility limit of dioctyl phthalate with poly (ethylene oxide) is 15 wt%.298 Free volume increases linearly with the amount of plasticizer increasing but crystallinity of polymer changes only little. This shows that plasticizer modifies mostly amorphous phase. Figure 11.24.
