It is synthesized by destructive nitration of 2,4,6-tricarboxyl-1,3,5-triazine. It is noteworthy for having more nitro groups than it does carbon atoms, thus potentially being useful as an oxygen source, or added to oxygen-poor explosives to increase their power.
1,3,5-Trimethyl-1,3,5-triazinane is an organic compound with the formula (CH 3 NCH 2) 3. It is a colorless liquid that is soluble in many organic solvents. Structurally, it is one of several related hexahydro-1,3,5-triazines, which typically result from the condensation reaction of amines and formaldehyde.
1,3,5,7-Tetramethyl-1,3,5,7-tetrasilaadamantane is the organosilicon compound with the formula (CH 2) 6 (SiCH 3) 4. It is a colorless solid that is soluble in organic solvents. The compound is one of the iconic carbosilanes, featuring alternating −Si−C−Si−C− linkages. [2] Otherwise it can be described as a diamondoid cluster.
Toxic units (TU) are used in the field of toxicology to quantify the interactions of toxicants in binary mixtures of chemicals. [1] A toxic unit for a given compound is based on the concentration at which there is a 50% effect (ex. EC50) for a certain biological endpoint. One toxic unit is equal to the EC50 for a given endpoint for a specific ...
N,N',N''-trisubstituted hexahydro-1,3,5-triazines arise from the condensation of a primary amine and formaldehyde as illustrated by the route to 1,3,5-trimethyl-1,3,5-triazacyclohexane: 3 CH 2 O + 3 H 2 NMe → (CH 2 NMe) 3 + 3 H 2 O. The C-substituted derivatives are obtained by reaction of aldehydes and ammonia: [1] 3 RCHO + 3 NH 3 → (RCHNH ...
The compound was first synthesized in 1924 by Oldřich Turek. [3] It can be prepared by the reaction of 1,3,5-trichloro-2,4,6-trinitrobenzene with sodium azide. 1,3,5-trichloro-2,4,6-trinitrobenzene is obtained from the nitration of 1,3,5-trichlorobenzene with nitric acid and sulfuric acid. [3]
Trinitrobenzene is more explosive than TNT, but more expensive. [2] It is primarily used as a high explosive compound for commercial mining and military applications. It has also been used as a narrow-range pH indicator, an agent to vulcanize natural rubber, and a mediating agent to mediate the synthesis of other explosive compounds.
