The separation of hydroquinone and hydroquinone formaldehyde can be achieved by distillation. The boiling point of hydroquinone is about 250℃, while that of hydroquinone formaldehyde is about 140℃. Therefore, the two can be separated by distillation. The distillation process is as follows: first, the mixture of hydroquinone and hydroquinone formaldehyde is heated to a temperature higher than the boiling point of hydroquinone, and then the vapor is collected and cooled to a temperature lower than the boiling point of hydroquinone formaldehyde. The hydroquinone will condense and be collected, while the hydroquinone formaldehyde will remain in the vapor state and be collected separately.
