Изобретение относитс  к области химической обработки древесины и касаетс  способа |М.одификации древесины путем ее ацетилировани .The invention relates to the field of chemical processing of wood and relates to the method of | M. wood modification by acetylation.

Известны способы модификации древесины путем ее адетилировани , например уксусным ангидридом.Methods are known for modifying wood by adapting it, for example, with acetic anhydride.

Однако известные способы не позвол ют значительно сократить продолжительвость процесса и повысить качество модифицированной древесины.However, the known methods do not significantly reduce the duration of the process and improve the quality of the modified wood.

Целью изобретени   вл етс  создание такого способа модификации древесины, который позволил бы сократить врем  и повысить качество модифицированной древесины при ее ацетилировании.The aim of the invention is to create such a method for modifying wood, which would reduce the time and improve the quality of the modified wood when it is acetylated.

Дл  достижени  этой цели используют способ модификации древесины путем ее ацетилировани , например, уксусным ангидридом.To achieve this goal, a method of modifying wood by acetylation is used, for example, with acetic anhydride.

Дл  этого в уксусный ангидрид предварительно ввод т 0,25-1% ангидрона, а затем производ т ацетилирование древесины при температуре 80-120° С в течение 0,,0 час.For this purpose, 0.25-1% anhydron is pre-introduced into acetic anhydride, and then acetylation of wood is performed at a temperature of 80-120 ° C for 0, 0 hours.

Способ осуществл ют следующим образом.The method is carried out as follows.

В уксусный ангидрид предварительно перед ацетилированием добавл ют 0,25-1% ангидрона Mg (0104)2, затем производ т ацетилирование в автоклаве при температуре 80- 120° О в течение 0,5-2,0 час. После этого образцы вынимают из автоклава, высушивают и определ ют степень ацетилировани .Before acetylation, 0.25-1% of Mg (0104) 2 anhydron is added to acetic anhydride, then acetylated in an autoclave at a temperature of 80-120 ° C for 0.5-2.0 hours. Thereafter, the samples are removed from the autoclave, dried, and the degree of acetylation is determined.

Предмет изобретени Subject invention

Способ модификации древесины путем ее ацетилировани , например уксусным ангидридом , отличающийс  тем, что, с целью сокращени  продолжительности технологического процесса и повышени  качества модифицированной древесины, в уксусный ангидрид предварительно ввод т 0,25-1% ангидрона , а затем производ т ацетилирование древесины при температуре 30-120° С в течение 0,5-2,0 час.A method of modifying wood by acetylating it, for example with acetic anhydride, characterized in that, in order to reduce the duration of the technological process and improve the quality of the modified wood, 0.25-1% anhydron is introduced into the acetic anhydride and then acetylated wood is produced at a temperature 30-120 ° C for 0.5-2.0 hours.
