What is US2818442 Paten Reaksi about?
The document describes a patented method for preparing pentaerythritol by reducing the free formaldehyde content in the reaction liquor through rapid heating at 85-100°C for a short duration of 1 to 15 minutes. This method significantly decreases the formaldehyde and alkali content, allowing for efficient recovery of pentaerythritol while maintaining high yields. The process is suitable for both continuous and batch production, improving efficiency and reducing chemical costs compared to traditional methods
