Iso Butanol

Iso Butanol is a clear, colourless mobile solvent. It is a naturally occurring four-carbon alcohol which has a low boiling point and a sweet, musty odour. It is miscible with common solvents such as alcohols, ketones, aldehydes, ethers, glycols and aromatic and aliphatic hydrocarbons but it has only limited miscibility in water.

Synonyms: 2-methylpropan-1-ol, isobutyl alcohol, IBA, 2-methyl-1-propanol, natural iso butyl alcohol, 2-Methyl propanol, FEMA 2179, isobutanol; isobutanol, 2-methyl-1-propanol

Applications of Iso Butanol

Iso Butanol is used as a solvent and a feedstock for chemical syntheses. It is widely used as a diluent in cellulose nitrate lacquers as it improves their flow, gloss and resistance to blushing. It is suitable for use as a solvent for acid-curable lacquers and baking finishes derived from urea, melamine, or phenolic resins, where it is mainly used together with glycol ethers, ethanol or aromatic hydrocarbons.

It is used in the manufacture of solvent coatings and cleaners, textiles, de-icing fluids, flotation agents, floor polishes, as a gasoline additive, in anti-corrosion and anti-wear inhibitors for engine oils, as an intermediate for glycol ethers, esters and agricultural chemicals, as an extractant in the manufacture of drugs, antibiotics, hormones and vitamins and as a solvent for printing inks.

Iso butanol is increasingly used to replace petroleum-based products as it is chemically equivalent and derived from renewable sources.

Storage and Handling

Iso butanol is a flammable liquid; keep away from excessive heat and sources of ignition.Eye contact with iso butanol can with cause irritation, redness and blurred vision. Iso butanol is a skin irritant which may cause dermatitis if exposure is prolonged. Ingestion may cause nausea, vomiting and diarrhoea.  Excessive inhalation of the vapour or mist may cause irritation to the respiratory system and depress the central nervous system. Appropriate precautions including adequate ventilation and the wearing of the necessary personal protective equipment such as impermeable gloves and body suit and eye goggles must be observed to avoid exposure.

Iso butanol should be stored below 40°C in humidity-free conditions away from strong oxidants. In these conditions, it can be expected to remain stable and have a storage life of at least one year.
