为了研究乙酰化木材对有机液体的亲和性，将乙酰化云杉木材浸泡在各种液体中，并将其与未处理的木材进行比较。乙酰化的木材在具有低氢键力的液体如苯和甲苯中迅速且显著地溶胀，而未处理的木材仅轻微或非常缓慢地溶胀。另一方面，木材在水、乙二醇和醇中的溶胀体积在乙酰化后保持不变或略有下降。乙酰化的效果是更大的液体具有较小的溶解度参数。非质子有机液体更容易渗透到乙酰化木材中被认为是由于极性的降低和无定形木材组分中的氢键的断裂，其中亲水性羟基被疏水性乙酰基取代。
To investigate the affinity of acetylated wood for organic liquids, acetylated yezo spruce wood specimens were soaked in various liquids, and their swellings were compared to those of untreated specimens. The acetylated wood was rapidly and remarkably swollen in liquids having low hydrogen bonding power such as benzene and toluene in which the untreated wood was swollen only slightly or very slowly. On the other hand, the swollen volume of wood in water, ethylene glycol, and alcohols remained unchanged or slightly decreased after the acetylation. The effect of acetylation was greater in liquids having smaller solubility parameters. The easier penetration of aprotic organic liquids into the acetylated wood was considered to be due to the reduction of polarity and the scission of hydrogen bonds in the amorphous wood constituents where the hydrophilic hydroxyl groups were substituted by hydrophobic acetyl groups.
