To determine the various interactions between glutaraldehyde and glycols (hexylene and propylene), various thermodn. and acoustic properties have been analyzed by using the d. (ρ) and ultrasonic velocity (c) of liquid mixtures of (hexylene or propylene + aqueous glutaraldehyde solutions), resp., in the concentration ranges from (0.01 to 0.04) mol·kg-1 at the temperatures of 293.15, 298.15, 303.15, 308.15 K. Thermodn. parameters including the apparent molar volume (VΦ) and partial molar volume (V0Φ) have been calculated from the d. values. These parameters show that the (solute-solvent) interaction for propylene glycol is weaker as compared to hexylene glycol. Acoustic parameters including the apparent molar isentropic compressibility (KΦ,s) and partial molar isentropic compression (K0Φ,s) have been determined by using ultrasonic velocity values. Pair and triplet interaction coefficients have also been determined by using partial molar volume of transfer and partial molar isentropic compression of transfer. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6HPLC of Formula: 57-55-6).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.HPLC of Formula: 57-55-6
