Abstract: front page image
(EN)A method for the purification of 2-alkyl-2-adamantyl(meth)acrylates, which comprises: adding a polymerization inhibitor to a 2-alkyl-2-adamantyl (meth)acrylate; subjecting the resulting mixture to distillation; adding an alcoholic solvent to the 2-alkyl-2-adamantyl (meth)acrylate obtained by the distillation; and subjecting the mixture thus obtained to crystallization.
(FR)La présente invention concerne un procédé pour la purification de (méth)acrylates de 2-alkyl-2-adamantyle, qui comprend : l'ajout d'un inhibiteur de polymérisation à un (méth)acrylate de 2-alkyl-2-adamantyle ; la soumission du mélange résultant à une distillation ; l'ajout d'un solvant alcoolique au (méth)acrylate de 2-alkyl-2-adamantyle obtenu par la distillation ; et la soumission du mélange obtenu ainsi à une cristallisation.
(JA)2-アルキル-2-アダマンチル(メタ)アクリレートに、重合禁止剤を入れて蒸留し、前記蒸留した2-アルキル-2-アダマンチル(メタ)アクリレートに、アルコール系溶媒を添加して晶析する、2-アルキル-2-アダマンチル(メタ)アクリレートの精製方法。
