O=PCl 3 + 3 H 2 O → O=P(OH) 3 + 3 HCl. Intermediates in the conversion have been isolated, including pyrophosphoryl chloride, O(−P(=O)Cl 2) 2. [9] Upon treatment with excess alcohols and phenols, POCl 3 gives phosphate esters: O=PCl 3 + 3 ROH → O=P(OR) 3 + 3 HCl. Such reactions are often performed in the presence of an HCl acceptor such ...
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C 6 H 5) 3, also written as Ph 3 PO or PPh 3 O (Ph = C 6 H 5). It is one of the more common phosphine oxides. This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine.
PL or P/L: parts list: A list, usually tabular and often on the drawing (if not accompanying the drawing on a separate sheet), listing the parts needed in an assembly, including subparts, standard parts, and hardware. There is no consistently enforced distinction between an L/M, a BoM, or a P/L. PLM: product lifecycle management; plant ...
A phosphoryl group is a trivalent >P(=O)− group, consisting of a phosphorus atom (symbol P) and an oxygen atom (symbol O), where the three free valencies are on the phosphorus atom. While commonly depicted as possessing a double bond (P=O) the bonding is in fact non-classical. [1]
