of Dichlorophenol, Parachloroaniline (PCA) 1500 TPA, Parachloroaniline Hydrochloride
Rasayan, a Patel group company, was established in 1990,
with the initial production of Beta Naphthol. The company
diversified into Dichlorophenol, Paranitroaniline (PNA), Parachloroaniline
(PCA), Parachloroaniline Hydrochloride and 2,5 Dichloroaniline
and established manufacturing capacities of 1200 TPA of PNA
and 1500 TPA of PCA in 1994, company also produces PCA Hydrochloride
600 TPA and Dichloroaniline 600 TPA. Dichlorophenol may be released to the environment in effluents from dichlorophenol manufacture and use as a chemical intermediate and from chlorination processes involving water treatment and wood pulp bleaching. Dichlorophenol is stored as Provision to contain effluent from fire extinguishing. Separated from oxidants, food and feedstuffs. Ventilation along the floor.
may be released to the environment in effluents from its manufacture and use as a chemical
intermediate and from chlorination processes involving water treatment and wood pulp bleaching. Releases of Dichlorophenol,
can also occur from various incineration processes or from metabolism of various pesticides in soil. If released to the atmosphere, degradation can occur by reaction with photo chemically formed hydroxyl radicals. Physical removal of Dichlorophenol from air may occur via rainfall. With a pKa of 7.8, Dichlorophenol can exist in both the non-dissociated and ionized forms in environmental soil and water depending upon the pH of the media. If released to soil, moderate to slow leaching is possible based on observed Koc values of 200-5000; the ionized form appears more susceptible to leaching than the non-dissociated form. Various biodegradation studies have demonstrated that Dichlorophenol is biodegradable under aerobic and anaerobic conditions in both soil and water. If released to water, adsorption to sediments may be important under various conditions determined, in part, by pH. Photo degradation in natural water can occur by direct photolysis or by reaction with sunlight-formed oxidants (singlet oxygen and peroxy radicals). The general population can be exposed to Dichlorophenol through consumption of contaminated tap water or by inhalation of contaminated air.
