| titleOfInvention | PROCESS FOR THE PREPARATION OF DIPHOSPHASPIRO COMPOUNDS |
| abstract | PROCESS FOR PREPARING DIPHOSPHAPIRO COMPOUNDS. A PHOSPHONIC ACID OR AN ESTER OF PHOSPHONIC ACID OF FORMULA: (CF DRAWING IN BOPI) IS REACTED WITH A PHOSPHONIC ACID DICHLORIDE OF FORMULA: (CF DRAWING IN BOPI) SO AS TO OBTAIN A PHOSPHONIC ANHYDRIDE OF FORMULA: (CF DRAWING IN BOPI) AND, POSSIBLY WITHOUT ISOLATING THIS ANHYDRIDE, IT IS REACTED WITH PENTAERYTHRITOL. COMPOUNDS OF THE FORMULA (CF DRAWING IN BOPI) ARE THUS OBTAINED IN THE PREVIOUS FORMULAS R REPRESENTS AN ALKYL, PHENYL, BENZYL OR CYCLOHEXYL RADIAL AND R AND R EACH REPRESENT A HYDROGEN ATOM OR A METHYL OR ETHYL RADIAL. THESE DIPHOSPHASPIRO COMPOUNDS CAN BE USED IN PARTICULAR AS FIRE RETARDERS FOR POLYMERS. |
