N,N'-Diphenyl-p-phenylenediamine's production and use as an antioxidant in rubbers may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 6.35X10-9 mm Hg at 25 °C indicates N,N'-diphenyl-p-phenylenediamine will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase N,N'-diphenyl-p-phenylenediamine will be

p-Phenylenediamine (PPD) is an organic compound with the formula C 6 H 4 (NH 2) 2.This derivative of aniline is a white solid, but samples can darken due to air oxidation. It is mainly used as a component of engineering polymers and composites like kevlar.It is also an ingredient in hair dyes and is occasionally used as a substitute for henna.
N,N'-DIPHENYL-P-PHENYLENEDIAMINE may react with oxidizing materials (NTP, 1992). Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with
This database contains substances that have been assigned hazard property (HP) waste codes 1-15, as defined in terms of the hazard class & category, hazard (H) statement, and/or concentration limits provided in Annex III of the Waste Framework Directive (2008/98/EC). The classifications of the substances listed in the database are based on their harmonized classifications per Table 3 of Annex
While used primarily for ozone resistance, it is a more active antioxidant than quinoline or diphenylamine based antioxidants. The product provides compound protection against catalytic degradation by copper and other heavy metals. The product has no negative effects on compound adhesion to textiles or steel cord up to levels of 2 phr. Above this concentration it may bloom and interfere with

General description Tris(2-carboxyethyl)phosp hine hydrochloride (TCEP.HCl) is a non-volatile solid. It is a strong reducing agent.1 It can be synthesized by the acid hydrolysis of tris(2-cyanoethyl)phosphi ne in refluxing aqueous HCl.1 It has various biological applications such as in vitro and in vivo reduction of disulfide bonds in various peptides and proteins.1 TCEP is a useful chelating
The sulfenamide class accelerators include CBS, TBBS, MBS, DCBS etc. and are most popular in the tire industry due to their delayed action as well as faster cure rateoffered by them during vulcanization of rubber compounds containing furnace blacks. The sulfenamide accelerators are the reaction products of 2 Mercaptobenzothiazole with- basic amines such as Cyclohexylamine / Tert-Butylamine
To conduct a systematic review and meta-analyses of published studies examining the association between myeloid leukemias (ML) and occupational pesticide exposure.

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
