1,3,5-Trichlorobenzene is an organochlorine compound. It is one of the three isomers of trichlorobenzene. Being more symmetrical than the other isomers, it exists as colourless crystals whereas the other isomers are liquids at room temperature. It is not formed upon chlorination of benzene. Instead it is prepared by the Sandmeyer reaction from ...
In Canada, the use and sale of 2,4,5-T was prohibited after 1985. [5] The international trade of 2,4,5-T is restricted by the Rotterdam Convention. 2,4,5-T has since largely been replaced by dicamba and triclopyr. Human health effects from 2,4,5-T at low environmental doses or at biomonitored levels from low environmental exposures are unknown.
4-Phenyl-1,2,4-triazoline-3,5-dione (PTAD) is an azodicarbonyl compound. PTAD is one of the strongest dienophiles and reacts rapidly with dienes in Diels-Alder reactions. [ 1] The most prominent use of PTAD was the first synthesis of prismane in 1973. [ 2]
3,5,5-Trimethyl-hexan-1-ol. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 3,5,5-Trimethyl-1-hexanol is a nine carbon primary alcohol, and it makes up the mixture isononanol along with isononyl alcohol. It is used for fragrance in many toiletries and household cleaning products.
1,3,5-Trithiane is the chemical compound with the formula (CH 2 S) 3. This heterocycle is the cyclic trimer of the otherwise unstable species thioformaldehyde. It consists of a six-membered ring with alternating methylene bridges and thioether groups. It is prepared by treatment of formaldehyde with hydrogen sulfide.
The Ehrhardt 7.5 cm Model 1901 (Also known as the 7.5 cm feltkanon m/01 or the M/01 7.5 cm (2.95 in) field gun) was a field gun designed and built by the German company Rheinische Metallwaren- und Maschinenfabrik and sold to Norway in 1901. It remained the main field artillery gun of the Norwegian Army until the German invasion of Norway in ...
