How do you make dioctyl phthalate?

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.

Is DOP a phthalate?

Di-n-octyl phthalate (DOP) is the straight chain isomer of di(2-ethylhexyl) phthalate (DEHP) which is a widely used plasticizer and an environmental contaminant. DEHP is a strong inducer of peroxisome proliferation in rat liver.

What is BIS 2 ethylhexyl phthalate used for?

Use in medical devices DEHP is the most common phthalate plasticizer in medical devices such as intravenous tubing and bags, IV catheters, nasogastric tubes, dialysis bags and tubing, blood bags and transfusion tubing, and air tubes.

What are plasticizers made of?

What are they made of? Plasticizers are produced by a reaction of an alcohol with an acid such as adipic acid, phthalic anhydride, and so forth. The choice of alcohol and acid will determine the type of ester that can be produced and hence the kind of plasticizer.

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.

Is dioctyl phthalate harmful?

CARCINOGEN and TERATOGEN in humans. There may be no safe level of exposure to a carcinogen, so all contact should be reduced to the lowest possible level.

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 dioctyl Orthophthalates?

Description Dioctyl orthophthalates are used in certain types of paints, caulks, plastics, and rubber products.

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 the molecular weight of di-n-octyl phthalate?

Dioctyl phthalate PubChem CID 8346 Synonyms Dioctyl phthalate DI-N-OCTYL PHTHALATE 1 Molecular Weight 390.6 Date s Modify 2021-06-26 Create 2005-03-26

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.

Is plasticization of unsaturated polyester resin using dioctyl phthalate useful?

The effect of plasticization of unsaturated polyester resin using dioctyl phthalate was investigated. The plasticized and un-plasticized polyester were characterized for impact strength, tensile strength, modulus of elongation, modulus of rupture and, thermal stability.

What is Didi-N-octylphthalate?

Di- n- octylphthalate is a colorless, odorless, oily liquid that doesn’ t evaporate easily. It is a man- made substance used to keep plastics soft or more flexible. This type of plastic can be used for medical tubing and blood storage bags, wire and cables, carpetback coating, floor tile, and adhesives. It is also used in cosmetics and pesticides.
