Saturated　vapor　pressures　of　acetone　oxime　methyl　ether(AOME)　were　measured　in　the　temperature　range　of　307.75~344.05　K　by　dynamic　method　in　a　Rose　still.　The　measured　saturated　vapor　pressures　and　temperatures　were　correlated　by　Antoine　equation　and　the　constants　of　equation　were　determinated　as　A　=　20.64,　B　=　2338.72,　and　C　=　-88.86　by　nonlinear　regression　method.　The　averaged　relative　error　between　saturated　vapor　pressures　calculated　from　the　Antoine　equation　and　the　experimental　data　is　0.45%.　Based　on　the　experimental　data　of　vapor　pressures,　the　latent　heat　of　vaporization　of　acetone　oxime　methyl　ether　was　also　obtained　by　Clausius-Clapeyron　equation　and　its　value　is　36479.24　kJ·kmol-1　in　the　temperature　range　of　307.75~344.05　K.　It　is　very　important　to　provide　the　Antoine　constants　and　latent　heat　of　acetone　oxime　methyl　ether　for　the　design　and　operation　of　its　distillation　separation　process.
