Isobutyraldehyde is the chemical compound with the formula (CH 3) 2 CHCHO. It is an aldehyde, isomeric with n-butyraldehyde (butanal). [1] Isobutyraldehyde is made, often as a side-product, by the hydroformylation of propene. Its odour is described as that of wet cereal or straw. It undergoes the Cannizaro reaction even though it has alpha ...
It is produced by the condensation reaction of isobutyraldehyde and two equivalents of urea: (CH 3) 2 CHCHO + 2 OC(NH 2) 2 → (CH 3) 2 CHCH{NHC(O)NH 2} 2 + H 2 O. The controlled-release process is the reverse of the above reaction, which only occurs after the IBDU dissolves.
Butyraldehyde undergoes reactions typical of alkyl aldehydes, and these define many of the uses of this compound.Important reactions include hydrogenation to the alcohol, oxidation to the acid, and base-catalyzed condensation.
Isobutyric acid is manufactured by the oxidation of isobutyraldehyde, which is a byproduct of the hydroformylation of propylene. [7] It can also be prepared by the high pressure hydrocarboxylation (Koch reaction) from propylene: [7] CH 3 CH=CH 2 + CO + H 2 O → (CH 3) 2 CHCO 2 H

This is a list collecting the most notable films produced in Hungary and in the Hungarian language during 1901–1948.. While the first years of the Hungarian cinema were in its infancy with mostly experimental films and short comedic sketches mostly conducted by enterprising hobbyists, by 1940 a large industry grew out of their footsteps, with famed film star idols and film studios.
Bulcsú (Sándor Csányi) is a ticket inspector on the underground; he spends his nights sleeping on the train platforms, and never leaves the underground.His ragtag team of inspectors – consisting of the veteran Professzor (Zoltán Mucsi), the disheveled Lecsó (Sándor Badár), neurotic narcoleptic Muki (Csaba Pindroch) and dimwitted greenhorn Tibi (Zsolt Nagy) – is routinely ...
