CAS:1314-56-3|五氧化二磷
【产品介绍】:
五氧化二磷可通过使磷与空气发生反应而制备得到。它在有机合成中常用作脱水和缩合剂。 Phosphorus pentoxide is a dehydrating agent often used as a dessicant for bacterial cultural extracts analyzed by gas-liquid chromatography. 五氧化二磷/甲磺酸(PPMA)可用作缩合剂和溶剂,用于合成: • 高分子量聚(苯并恶唑),其可通过含有苯基醚结构的芳族二羧酸与3,3′-二羟基联苯胺二盐酸盐的直接缩聚反应制得。 • 芳族聚苯醚醚酮,其可通过4-(4′-苯氧基苯氧基)苯甲酸.P8}的直接自缩聚反应制得。 • 1,3-1H-双苯并咪唑-苯,其可通过间苯二甲酸与1,2-二氨基苯反应制得。 五氧化二磷可被用于1-甲基-2-吡咯烷酮(NMP)的真空蒸馏,其可在色谱分析中用作流动相。 它可用作合成二氯七氧化二氯(Cl2O7)和过渡金属磷化物(Ni2P、Co2P和MoP)的反应组分之一。氧化铝上负载的P2O5可用于1,5-苯并二氮杂类似物的无溶剂和微波辅助制备。P2O5/KX(X = Br, I)试剂体系可用于将醇转化为相应的烷基碘和溴化物。 Phosphorus pentoxide can be prepared by reacting phosphorus with air. It is commonly used as a dehydrating and condensing agent in organic synthesis. Phosphorus pentoxide is a dehydrating agent often used as a dessicant for bacterial cultural extracts analyzed by gas-liquid chromatography. Phosphorus pentoxide may be used for the vacuum distillation of 1-methyl-2-pyrrolidinone (NMP), which was employed as mobile phase in a chromatographic analysis. It may be used as one of the reaction components in the synthesis of dichlorine heptoxide (Cl2O7) and transition-metal phosphides (Ni2P, Co2P and MoP). P2O5 supported on alumina can be used for the solvent-free and microwave-assisted preparation of 1, 5-benzodiazepine analogs. P2O5/KX (X = Br, I) reagent system may be used for the transformation of alcohols into the corresponding alkyl iodides and bromides. Phosphorus pentoxide/methanesulfonic acid (PPMA) may be used as a condensing agent and solvent for the synthesis of: • High molecular weight poly(benzoxazole)s via direct polycondensation of aromatic dicarboxylic acids containing phenyl ether structure with 3,3′-dihydroxybenzidine dihydrochloride. • Aromatic poly(phenylene ether ether ketone)s via direct self-polycondensation of 4-(4′-phenoxyphenoxy)benzoic acids.P8} • 1,3-1H-dibenzimidazole-benzene by the reaction of isophthalic acid with 1,2-diaminobenzene.产品名称 五氧化二磷 产品名称 Phosphorus pentoxide 别名 磷酐 英文别名 Phosphoric anhydride; Phosphorus oxide CAS编号 1314-56-3 分子式 P2O5 分子量 141.94 PubChem CID 56370677 MDL号 MFCD00011440 IIUPAC Name O=P(=O)OP(=O)=O INCHI InChI=1S/O5P2/c1-6(2)5-7(3)4 InChi Key YWEUIGNSBFLMFL-UHFFFAOYSA-N UN Number 1807 EC号 215-236-1 Reaxys-RN 11323962 Merck Index 7355 Class 8 Packing group II 规格或纯度 powder,ACS,≥98.0% 应用 五氧化二磷/甲磺酸(PPMA)可用作缩合剂和溶剂,用于合成: · 高分子量聚(苯并恶唑),其可通过含有苯基醚结构的芳族二羧酸与3,3′-二羟基联苯胺二盐酸盐的直接缩聚反应制得。 · 芳族聚苯醚醚酮,其可通过4-(4′-苯氧基苯氧基)苯甲酸.P8}的直接自缩聚反应制得。 · 1,3-1H-双苯并咪唑-苯,其可通过间苯二甲酸与1,2-二氨基苯反应制得。 五氧化二磷可被用于1-甲基-2-吡咯烷酮(NMP)的真空蒸馏,其可在色谱分析中用作流动相。 它可用作合成二氯七氧化二氯(Cl2O7)和过渡金属磷化物(Ni2P、Co2P和MoP)的反应组分之一。氧化铝上负载的P2O5可用于1,5-苯并二氮杂类似物的无溶剂和微波辅助制备。P2O5/KX(X = Br, I)试剂体系可用于将醇转化为相应的烷基碘和溴化物。 沸点 360°C 熔点 340°C 敏感性 对湿度和空气敏感 溶解性 Soluble in H2SO4.
