Butanal Use and Manufacturing
Methods of Manufacturing
From butyryl chloride; by redn of corresponding nitrile; by alkali aluminum hydride redn of methyl butyrate. Usually mfr by catalytic dehydrogenation of butanol, catalytic hydrogenation of crotonaldehyde, or by the oxo process from propene.|By dry distillation of calcium butyrate & calcium formate.|The most widely used manufacturing technique for butyraldehyde is the oxo process, in which propylene, carbon monoxide, and hydrogen are combined with a suitable catalyst, usually a cobalt compound, at about 130-160 °C and 100-200 atm pressure. Butyraldehyde can also be produced from 2-butenal (crotonaldehyde) formed by the Aldol condensation of acetaldehyde. This process was a major source of butyraldehyde until about 1970.|Propylene + synthesis gas (hydroformylation; coproduced with isobutylaldehyde)|For more Methods of Manufacturing (Complete) data for BUTYRALDEHYDE (6 total), please visit the HSDB record page.

Uses
n-Butyraldehyde is used to make rubberaccelerators, synthetic resins, and plasticizers;and as a solvent. Chiefly in the manufacture of rubber accelerators, synthetic resins, solvents, plasticizers.

Handling and Storage

Precautions for safe handling

NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

Fireproof. Separated from incompatible materials. See Chemical Dangers. Cool. Keep in the dark. Store in an area without drain or sewer access.On contact with air butyraldehyde is oxidized readily to the butyric acids. Therefore, storage under inert gas is mandatory.
