Density of solutions of formaldehyde in water and alcohols

Formaldehyde is an important chemical that mostly handled in aqueous solutions, which generally also contain methanol; furthermore, solutions of formaldehyde other alcohols are used. The density these thermophysical property. available models the formaldehyde-containing however, all have shortcomings, such as a poor accuracy or limited range applicability. Therefore, present work, new model systems type (formaldehyde + water alcohol) was developed. presently included methanol, 1-propanol, and isoprenol; extension to straightforward. developed using literature data extensive measured this work covering binary, ternary, quarternary water, isoprenol at temperatures 283 − 333 K concentrations 0.06 0.30 g g−1.
