| abstract | 552,061. Organic phosphinous acids. ABBEY, A. (Siegfried, Ltd., B.). Sept. 18, 1941, No. 12000. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 29, 1942.] [Class 2 (iii)] Organic phosphinous acids and their salts of the formula R-CH(OH)-P(OH) 2 where R is an organic radical are prepared by reaction of hypophosphorous acid with aldehydes at 50- 60‹C. in concentrated solution. Examples are given of the preparation of α-hydroxybenzylphosphinous acid, which is a strongly acting toxic, from benzaldehyde, sodium salt of metaxyl - dialpha - hydroxyphosphinous acid from isophthalic aldehyde, sodium salt of hydroxy-camphor phosphinous acid from oxymethylene camphor, hydroxy - oenanthylic - phosphinous acid from oenanthic aldehyde, the plumbate being first formed, and hydroxyisoamylic-phosphinous acid from isovalericaldehyde Snd 80-82 per cent. hypophosphorous acid in each case. |
