दम घोंटने वाला एक रंगहीन द्रव जो ऐल्कोहल के ऑक्सीकरण से बनता है में डुबोना या तर करना, हवा में उड़ जाने वाला, एल्डिहाइड,

aldehyde's Usage Examples:

hydroxylamine gives the dioxime of succinic aldehyde.

it is equal to the sum of the thermal effects of the aldehyde and carbonyl groups.

The thermal effect of the aldehyde group has the average value 64.88 calories, i.e.

Torray's observations on nitromalonic aldehyde, N02 CH(CHO)2,formed by acting on mucobromic acid, probably CHO CBr:CBr:000H, with alkaline nitrites; this substance condenses with acetone to give p-nitrophenol, and forms [I.3.5]-trinitrobenzene when its sodium salt is decomposed with an acid.

5]- ethylisophthalic acid, and with butyric aldehyde the corresponding propylisophthalic acid.

2 3, p. 2 377) investigated the condensation of pyroracemic acid, CH 3 CO 000H, with various aliphatic aldehydes, and obtained from two molecules of the acid and one of the aldehyde in the presence of baryta water alkylic isophthalic acids: with acetaldehyde [1.3.51-methylisophthalic acid or uvitic acid, C 6 H 3 CH 3 (000H) 2, was obtained, with propionic aldehyde [1.3.

4]-trimethylbenzene or pseudocumene; and of the condensation product of two molecules of isovaleryl aldehyde with one of acetone, C 3 H 7 CH 2 CH:C(C 3 H 7) CH:CH CO.

By the action of hydroxylamine or phenylhydrazine on aldehydes or ketones, condensation occurs between the carbonyl oxygen of the aldehyde or ketone and the amino group of the hydroxylamine or hydrazine.

According to this theory a " chemical type " embraced compounds containing the same number of equivalents combined in a like manner and exhibiting similar properties; thus acetic and trichloracetic acids, aldehyde and chloral, marsh gas and chloroform are pairs of compounds referable to the same type.

Duclaux found that acetic acid is formed in small quantities during fermentation; aldehyde has also been detected.
