有冇人知Butan-1-OI既boiling point 係機多(at standard pressure) ??

The boiling point and melting point of butan-1-ol are 117oC and -90oC respectively.

The major sources of error in measuring boiling points and melting points are :
(1) The sample contains impurities (including moisture) which gives a lower melting point and a higher boiling point.
(2) The reading error in reading temperature
(3) Incorrect recognization of boiling/melting
