Abstract
Procédé pour l'obtention en continu d'alcoolates alcalin par alcoolyse d'alcoolates alcalins d'alcools inférieurs, en particulier de méthanol ou d'éthanol, avec des alcools supérieurs introduits en excès, notamment des monoalcools aliphatiques ou cycloaliphatiques,et élimination de l'alcool à bas point d'ébullition. L'alcoolyse et la purification par distillation de l'alcool inférieur sont réalisées simultanément dans un dispositif comportant une section réactionnelle et une section de rectification directement couplée à celle-ci. Fabrication industrielle d'alcoolates alcalins.
