Aniline is toxic by inhalation of the vapour, ingestion, or percutaneous absorption. [41] [42] The IARC lists it in Group 2A (Probably carcinogenic to humans), and it has specifically been linked to bladder cancer. [43] Aniline has been implicated as one possible cause of forest dieback. [44] Many methods exist for the detection of aniline. [45]
The general population may be exposed to 2,4,6-trichloroaniline via drinking water and dermal contact with this compound in dyestuffs, pigments, and pesticides containing 2,4,6-trichloroaniline. [4] 2,4,6-trichloroaniline can be toxic when inhaled or ingested orally. The lethal dose is 2400 mg/kg for a rat. [1]
Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds. The K and B bands arise from π to π* transitions as a result of the a group containing multiple bond being attached to the benzene ring. When dissolved in ethanol, λ max for aniline is 230 nm, but in dilute aqueous acid λ max is 203 nm ...
Noxious weeds can be deadly for humans, animals and other plants in your garden. Here’s how to identify a plants before you get hurt. You may have poison in your garden.
These plants are extremely toxic. Spotted Water Hemlock is internally poisonous (ingesting can be fatal), and giant hogweed is both internally and externally poisonous. Touching this plant can ...
General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2] Changes to plant metabolism and growth are the result of disrupted physiological functioning, including inhibition of photosynthesis , water and nutrient uptake, cell division , or seed germination .
N-Methylaniline (NMA) is an aniline derivative. It is an organic compound with the chemical formula C 6 H 5 NH(CH 3). The substance is a colorless viscous liquid, Samples turn brown when exposed to air. The chemical is insoluble in water.
Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
