An ultrasonic exploration of physico-chemical properties for mixtures of dichloroacetyl chloride with polar, non-polar and polymers at 300 K

The present study is oriented towards the demonstration of physico-chemical properties and molecular interactions of the prepared binary mixture of Dichloroacetyl chloride (DCAC) with methanol/ethanol/CCl ₄ / PEGs through ultrasonic non-destructive characterization. The intermolecular interaction, structural ordering, and corrosiveness aspects of prepared binary mixtures have been interpreted on the basis of measured (density, viscosity, ultrasonic velocity) and estimated thermo-physical quantities (compressibility, free length, free volume, Gibb's free energy, thermal relaxation time, and ultrasonic absorption) at 300K. All binary mixtures have been received to undergo exothermic reaction during preparation while mixture DCAC + methanol has been found to produce excessive heat and harmful odour vapour. The study confirms that DCAC+CCl ₄ consist of least intermolecular interaction while mixture DCAC with PEG600 possesses strong molecular interaction among constituents accomplished by intense hydrogen bonding and physical forces. It also concludes that DCAC + PEG600 shall be highly viscous and least corrosive in comparison to other prepared mixtures. The present study provides new dimension for applicability of hazardous chemical DCAC in mixture form toward herbicides, pesticides, and fertilizers industries.
