Product Overview

Applications

Documented applications: Uses: Congress has permanently banned three types of phthalates (DEHP, DBP, BBP) in any amount greater than 0.1 percent (computed for each phthalate, individually) in (1) children's toys and (2) certain child care articles. di-(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), or benzyl butyl phthalate (BBP)., For bis(2-ethylhexylphthalate) (USEPA, OPP Pesticide Code: 295200) there are 0 labels match., SRP: Not registered for current use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses., The active ingredient is no longer contained in any registered pesticide products ... "cancelled.", Plastics may contain from 1 to 40% di(2-ethylhexyl) phthalate by weight and are used in consumer products such as imitation leather, rainwear, footwear, upholstery, flooring, wire and cable, tablecloths, shower curtains, food packaging materials and children's toys. ... Di(2-ethylhexyl) phthalate is also used as a hydraulic fluid and as a dielectric fluid (a non-conductor of electric current) in electrical capacitors., For more Uses (Complete) data for BIS(2-ETHYLHEXYL) PHTHALATE (19 total), please visit the HSDB record page., Plastics -> Typical concentration range in plastic materials -> 2.0 - 35.0%, DEHP is present in plastic products such as wall coverings, floor tiles, furniture upholstery, garden hoses, swimming pool liners, baby pants, dolls, some toys, shoes, automobile upholstery and tops, packaging film and sheets, sheathing for wire and cable, medical tubing, and blood storage bags.

Esterification is completed with an acid or metal catalyst or with no catalyst at high temperature., Preparation: P. J. Garner, G. Watson, United States of America patent 2508911 (1950 to Shell)., Di(2-ethylhexyl) phthalate is produced commercially by the reaction of excess 2-ethylhexanol with phthalic anhydride in the presence of an acid catalyst such as sulfuric acid or para-toluenesulfonic acid., Nonvolatile esters such as bis(2-ethylhexyl) phthalate can be obtained continuously by the following procedure: The mixture of acid or anhydride and alcohol together with sulfuric acid is introduced at the top of a plate column. An entrainer, e.g., benzene, is distilled through the column from below. The azeotrope of water and entrainer is drawn off the top and the ester accumulates in the sump., Impurities: ..., Data, indicate a high purity level (99.7%). The impurities found are mainly other phthalates., Formulations, Preparations: Trade names: FLEXOL Plasticizer DOP, Essochem DOP ...
