WebIn order to avoid the use of chloroform, the AOCS has developed an alternative method which uses isooctane as solvent, although the method is limited to PV < 70 meq/kg ( AOCS, 1998 ). The PV at which oxidation of oils can be detected as an off-flavour varies widely depending on the nature of the oil. WebThe replacement of acetic anhydride by mesyl chloride was necessary to ensure instant CO generation at room temperature (see the ESI † ). This replacement also contributes to the general safety aspects of the procedure, since mesyl chloride is a non-flammable chemical compared to acetic anhydride. prologic lock instructions
