In this study wool wax/lanolin recovery by green solvent was carried out using cyclopentyl methyl ether in comparison with conventional solvents like diethyl ether and hexan. The extraction study shows that cyclopentyl methyl ether shows higher amount of grease extraction in comparison with conventional solvents. Very big diffrence was found between the amount of wool grease from coarse wool both used for milk and meat production and fie wool from sheep breed for production of wool and meat. As shown by FTIR spectroscopy, the most principal and characteristic bands found in commercial lanolin spectra are also found in the extracted wax. Those bands belong to the organic acids, esters of organic acids and tertiary alcohols.

Abstract
In this study wool wax/lanolin recovery by green solvent was carried out using cyclopentyl methyl ether in comparison with conventional solvents like diethyl ether and hexan. The extraction study shows that cyclopentyl methyl ether shows higher amount of grease extraction in comparison with conventional solvents. Very big diffrence was found between the amount of wool grease from coarse wool both used for milk and meat production and fie wool from sheep breed for production of wool and meat. As shown by FTIR spectroscopy, the most principal and characteristic bands found in commercial lanolin spectra are also found in the extracted wax. Those bands belong to the organic acids, esters of organic acids and tertiary alcohols.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
