The Schedule 3 list is one of three lists. Chemicals which can be used as weapons, or used in their manufacture, but which have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 2 is used for chemicals which have legitimate small-scale applications. The use of Schedule 1, 2, or 3 chemicals as weapons is ...
Trimethyl phosphate is prepared by treating phosphorus oxychloride with methanol in the presence of an amine base: POCl 3 + 3 CH 3 OH + 3 R 3 N → PO(OCH 3) 3 + 3 R 3 NH + Cl −. It is a tetrahedral molecule that is a weakly polar solvent.
It is under supervision of Bangladesh Chemical Industries Corporation (BCIC). It primarily produces phosphate fertilizers. [1] [2] The factory complex consists of 2 units of TSP fertilizer producing facility with installed capacity of 1,52,000 MT (Unit-1; 32,000 MT and Unit-2; 1,20,000 MT). [3]
P(OCH 3) 3 → CH 3 P(O)(OCH 3) 2. As a ligand, trimethyl phosphite has a smaller cone angle and better acceptor properties relative to trimethylphosphine. A representative derivative is the colorless tetrahedral complex Ni(P(OMe) 3) 4 (m.p. 108 °C). [4] The tridentate ligand called the Kläui ligand is derived from trimethyl phosphite. The ...
They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite, P(OCH 3) 3. Some phosphites can be considered esters of the dominant tautomer of phosphorous acid (HP(O)(OH) 2). The simplest representative is dimethylphosphite with the formula HP(O)(OCH 3) 2. Both classes ...
Triethyl phosphate is an organic chemical compound with the formula (C 2 H 5) 3 PO 4 or OP(OEt) 3. It is a colorless liquid. It is a colorless liquid. It is the triester of ethanol and phosphoric acid and can be called "phosphoric acid, triethyl ester".
PCl 3 + 3 EtOH + 3 R 3 N → P(OEt) 3 + 3 R 3 NH + 3 Cl − In the absence of the base, the reaction of ethanol and phosphorus trichloride affords diethylphosphite ((EtO) 2 P(O)H). Of the many related compounds can be prepared similarly, triisopropyl phosphite is an example (b.p. 43.5 °C/1.0 mm; CAS# 116-17-6).
In 1982, it set up the first tiles factory in Bangladesh. [10] It is subsidized by Bangladesh government. [11] The Training Institute for Chemical Industries (TICI) is a sister concern of BCIC and is run by BCIC too. [12] Chittagong Urea Fertilizer School and College falls under this corporation, [13] as does Urea Sar Karkhana School & College ...
