Isoprene
Isoprene monomer is obtained by a two – step dehydrogenation of isopentane, by extractive rectification. It is chemically purified up to polymerization grade
MTBE
Synthesis of methyl -tert -butyl ether (MTBE) from methanol and isobutylene is an equilibrium exothermic reaction proceeding in the presence of acid – type catalyst – a sulfonated styrene – divinylbenzene copolymer.
Yellow Phosphorus
Yellow phosphorus is colorless wax-type crystal, with garlic odor. Insoluble in water, easily soluble in fat, carbon disulfide and other organic solvents. Spontaneous combustion in the air at room temperature and oxidiation into diphosphorus trioxide and phosphorus pentoxide so stored in water.
Phthalic Anhydride Flakes
Phthalic anhydride, the anhydride form of phthalic acid, is produced by the oxidation of orthoxylene and naphthalene. At room temperature it forms white crystals like flakes. In contact with water it results phthalic acid. Phthalic anhydride is used to make simple esters widely used as plasticizers.
Octanol (2-Ethyl-Hexanol)
Octanol (2-ethyl-hexanol) is a colorless liquid with a specific odor. The product is little soluble in water. It is combustible and flammable. On heating above 75° C octanol vapors give explosive mixtures with air. By heating to decomposition, 2-ethylhexanol gives carbon monoxide and dioxide. It can also give irritant and corrosive gases.
N-BUTANOL(Normal Butanol)
N-Butanol is a clear, colorless liquid with characteristic odor.
N-butanol is incompatible with strong oxidizers (permanganates, perhydrol).
It reacts with strong mineral acids.
ISO-BUTANOL(2 Methyl Propanol)
Iso- butanol is a colorless liquid with a characteristic odor. Mixed with air within 1.45-11.25% vol. limits. Iso- butanol forms explosive mixtures.
