Abstract:
      Corn wax was prepared from corn wax paste with acetone as extraction solvent.The effects of extraction time, extraction temperature, material-liquid ratio, stirring rate and extraction times on the extraction rate and purity of corn wax were investigated by single factor experiment. Then, on the basis of single factor experiment, the optimal process conditions were obtained by orthogonal experiment with purity and extraction rate of corn wax as indexes. The results showed that the optimal extraction conditions were obtained as follows: material-liquid ratio 1∶ 5, extraction temperature 50 ℃, extraction time 70 min, stirring rate 300 r/min, extraction 4 times. Under the optimal conditions, the extraction rate, purity, phospholipid content, whiteness, acid value, saponification value, moisture and volatile matter, melting range and acetone residues of corn wax were 66.71%, 97.23%, 0.18%, 59.86%, 0.99 mgKOH/g, 124.56 mgKOH/g, 0.03%, 68.01-81.98 ℃ and 14.98 mg/kg.
