| titleOfInvention | Novel lactone compound and method for producing the same |
| abstract | (57) [Summary] [Object] To find a substance capable of introducing a hydrophilic group without using ethylene oxide as a raw material of a surfactant, and to further provide a production method capable of industrially producing the substance at low cost. To provide. SOLUTION: 3,3-Digidroxymethylbutyrolactone or a derivative itself having a protected hydroxyl group (both are novel substances), and β-cyanopropionaldehyde and formaldehyde are reacted to form a tetrahydroxymethyl cyclized product, A process for obtaining the above derivative by once opening the ring and then closing the lactone form, reducing the formyl group to 3,3-dihydroxymethylbutyrolactone, and protecting the hydroxyl group thereof. |
