29.42 - Other organic compounds.
This heading covers separate chemically defined organic compounds not classified elsewhere.(1) Ketenes*. Like ketones, these are characterised by a carbonyl group (C=O) but it is linked to the neighbouring carbon atom by a double bond (e.g., ketene, diphenylketene). This heading however excludes diketene which is a lactone of heading 29.32. (2) Boron trifluoride complexes with acetic acid, diethyl ether or phenol*. (3) Dithymol di‑iodide.
