Uses

Enox DTBP (Di-tert-butyl peroxide) is a transparant liquid which has C8H18O2 as chemical formula.  This dialkyl peroxide is used as initiator for the production of Low Density Polyethylene (LDPE). Further it finds its application in the polymerization and copolymerization of styrene, olefins and acrylic resins and as modification agent of polypropylene degradation.

Di-tert-butyl peroxide is also known as DTBP, peroxide bis(1,1-dimethylethyl) and tert-Butyl peroxide. Di-tert-butyl peroxide is used for synthesis.

WGKWGK 1 slightly hazardous to water
Disposal10
Organic peroxides can be detected in aqueous solutions or organic solvents using the Perex-Test® (Cat. No. 116206). Pure peroxides are diluted to min. 10% in a suitable solvent or with water and added in small portions, with temperature control, to iron(II) chloride (Cat. No. 103860) solution. Test for complete reaction with the Perex-Test® (Cat. No. 116206). Container D. Explosive substances (storage class 4.1A) should be packed separately and tightly sealed for disposal. Ensure sufficient phlegmatization by water or the stated phlegmatizing agent!

Carcinogenicity

A single exposure (route unspecified, but probably subcutaneous (SC)) of 14.6 mg (~365 mg/kg) produced unconvincing evidence for carcinogenicity owing to the lack of controls in 50 mice observed for more than 80 weeks. Of 35 survivors, 7 (20%) had malignant blood tumors (lymphomas) and 1 had a benign lung tumor (pulmonary adenoma) (93, 7a). Owing to its poor design, this study should be judged inadequate to determine carcinogenicity.

Storage

Store in a cool and well-ventilated areaisolated from easily oxidizable materials.Protect against physical damage. Shippingcontainers are amber glass and polyethylenebottles or steel drums not exceeding 100-lbcapacity.
