Which of the following separation processes is most likely to yield high quality ethanol (>95%) from palm wine?
Fractional distillation without a dehydrant
simple distillation with a dehydrant
fractional distillation with a dehydrant
column chromatography
evaporation
คำอธิบาย
Fractional distillation with a dehydrant is the most likely separation process to yield high-quality ethanol from palm wine. Adding a dehydrant helps to remove water from the ethanol more effectively during the distillation process, resulting in a higher purity of ethanol. This is important for producing high-quality ethanol suitable for various applications, including consumption or industrial use.
