WebFeb 28, 2024 · Compounds can be broken down into smaller compounds, or their basic elements, by chemical change. Sometimes this chemical change requires energy in the form of heat or electricity. WebEnergy changes occur in chemical reactions as bonds are broken and new bonds formed. Enthalpy changes can be calculated from experimental data, and are independent of the route taken (Hess's Law).

Butyraldehyde, also known as butanal, is an organic compound with the formula CH3(CH2)2CHO. This compound is the aldehyde derivative of butane. It is a colorless flammable liquid with an unpleasant smell. It is miscible with most organic solvents. See more Butyraldehyde is produced almost exclusively by the hydroformylation of propylene: CH3CH=CH2 + H2 + CO → CH3CH2CH2CHO Traditionally, … See more Butyraldehyde undergoes reactions typical of alkyl aldehydes, and these define many of the uses of this compound. Important reactions include hydrogenation to the alcohol, oxidation to the acid, and base-catalyzed condensation. See more Aldol condensation in the presence of a base forms 2-ethyl-2-hexenal, which is then hydrogenated to form 2-ethylhexanol, a precursor to the … See more • International Chemical Safety Card 0403 See more how to scan models for 3d printer
