Ammonia is a colourless acrid-smelling gas at room temperature and normal atmospheric pressure. Most people can identify its odour at 35 mg/rn3 in air. It can be stored and transported as a liquid at a pressure of 10 ...

The first three sections of this Health and Safety Guide present essential technical information and the hazard evaluation. Section 4 includes advice on preventive and protective measures and emergency action; health workers ...

1,2-Dichioroethane is a colourless liquid, with a sweet taste aid a chloroform-like odour. Reportd odour thresholds are 25-450 mg/ni for perception and 162-750 mg/rn for recognition. 1,2-Dichiorethane is a volatile and ...

Brodifacoum is an off-white powder, which is stable in the solid form. Its solubility in water is very low (less than 10 mg/litre at 20 °C and pH 7); it is slightly soluble in benzene and soluble in acetone.

The PCBs are chlorinated hydrocarbons that are manufactured commercially by the progressive chlorination of biphenyl in the presence of a suitable catalyst (e.g., iron chloride). Depending on the reaction conditions, the ...

Diflubenzuron is an odourless, white, crystalline solid. It is almost insoluble in water and poorly soluble in apolar organic solvents. In polar to very polar solvents, the solubility is moderate to good, e.g., in acetone ...

Isobenzan is a whitish to light-brown crystalline powder, with a mild chemical odour. It is relatively stable to acids, but liable to dehydrochlorination under strongly alkaline conditions. Solubility in organic solvents: ...

Lindane is a white, crystalline solid, with a weak, or no, odour (the characteristic smell of technical HCH is attributed to the impurities, particularly heptachlorocyclohexane). Lindane is stable to light, air, heat, ...

Aldicarb has a slight sulfur smell. It has a melting point of 100 °C and a specific gravity of 1.195 at 25 °C. it is soluble in water, sensitive to heat, and relatively unstable. Analytical methods for aldicarb include ...

Commercial 1,3-dichioropropene is a mixture of cis- and trans- isomers and 92% pure. It may also be used in admixtures with 1 ,2-dibromoethane (Dorloe) or with 1 ,2dichloropropane (D-D , soil fumigant; Nemex Telone , and ...
