Nitrobenzene is prepared by nitration of benzene with a mixture of concentrated sulfuric acid, water, and nitric acid.This mixture is sometimes called mixed acid..The production of nitrobenzene is one of the most dangerous processes conducted in the chemical industry because of the exothermicity of the reaction (Î´ H = â117 kJ/mol). World capacity for nitrobenzene in 1985 was about 1.7Ã10 6 tonnes.his mixture is sometimes called mixed acid..

1 Parabens are absorbed in to the body. 2  In one study of Danish men, methyl-, ethyl-, n-propyl-and n-butyl parabens were measurable in 98%, 80%, 98% and 83% of the men, respectively. (Source) An American study found methyparaben in 99.1% of the study samples.he good news is that a lot of companies are reformulating their products without parabens because the word is getting out. The bad news is, though, that they're just replacing parabens with other harmful preservatives like diazolidinyl urea and tetrasodium EDTA.
