以碘价为54棕榈油为原料,采用干法分提制备棕榈油中间熔点物(POMF)。在单因素试验基础上,采用响应面优化实验,研究结晶温度、冷却速率和养晶时间对干法分提效果影响。得出棕榈油干法分提最佳工艺条件为:结晶温度16.83℃,冷却速率1.31℃/h,养晶时间13.39 h。在此条件下棕榈油中间熔点物(POMF)得率为30.3%,熔点为35.0℃,熔程为32℃~36℃。实验测定结果为:棕榈油中间熔点物(POMF)得率为29.9%,熔点为35.3℃,熔程为32℃~36℃。
以碘價為54棕櫚油為原料,採用榦法分提製備棕櫚油中間鎔點物(POMF)。在單因素試驗基礎上,採用響應麵優化實驗,研究結晶溫度、冷卻速率和養晶時間對榦法分提效果影響。得齣棕櫚油榦法分提最佳工藝條件為:結晶溫度16.83℃,冷卻速率1.31℃/h,養晶時間13.39 h。在此條件下棕櫚油中間鎔點物(POMF)得率為30.3%,鎔點為35.0℃,鎔程為32℃~36℃。實驗測定結果為:棕櫚油中間鎔點物(POMF)得率為29.9%,鎔點為35.3℃,鎔程為32℃~36℃。

Palm oil midfraction(POMF)was prepared by dry fractionation using palm oil(IV:54) as raw material. By response surface methodology on the basis of single factor experiments,we studied the effects of crystallization temperature,cooling rate and crystallization time. The optimized conditions were as follows:crystallization temperature of 16.83℃,cooling rate of 1.31℃/h,and crystallization time of 13.39 h. Under this condition,the yield of POMF was 30.3%,the melting point was 35.0℃,and the melting point range was between 32℃and 36℃. The experiment results were as follows:the yield of POMF was 29.9%,the melting point was 35.3℃,and the melting point range was between 32℃and 36℃.
