Polycaprolactone (PCL) is a synthetic, semi-crystalline, biodegradable polyester with a melting point of about 60 °C and a glass transition temperature of about −60 °C. [ 2 ] [ 3 ] The most common use of polycaprolactone is in the production of speciality polyurethanes .
The Point Cloud Library (PCL) is an open-source library of algorithms for point cloud processing tasks and 3D geometry processing, such as occur in three-dimensional computer vision. The library contains algorithms for filtering, feature estimation, surface reconstruction, 3D registration , [ 5 ] model fitting , object recognition , and ...
3 PhOH + PCl 3 → P(OPh) 3 + 3 HCl (Ph = C 6 H 5) Alcohols such as ethanol react similarly in the presence of a base such as a tertiary amine: [9] PCl 3 + 3 EtOH + 3 R 3 N → P(OEt) 3 + 3 R 3 NH + Cl −. With one equivalent of alcohol and in the absence of base, the first product is alkoxyphosphorodichloridite: [10] PCl 3 + EtOH → PCl 2 ...
The reaction of phosphorus pentoxide and PCl 5 produces POCl 3 : [18] [page needed] 6 PCl 5 + P 4 O 10 → 10 POCl 3. PCl 5 chlorinates nitrogen dioxide to form unstable nitryl chloride: PCl 5 + 2 NO 2 → PCl 3 + 2 NO 2 Cl 2 NO 2 Cl → 2 NO 2 + Cl 2. PCl 5 is a precursor for lithium hexafluorophosphate, LiPF 6.
Cover of Hare's Psychopathy Checklist-Revised (2nd ed., 2003). The Psychopathy Checklist or Hare Psychopathy Checklist-Revised, now the Psychopathy Checklist—revised (PCL-R), is a psychological assessment tool that is commonly used to assess the presence and extent of psychopathy in individuals—most often those institutionalized in the criminal justice system—and to differentiate those ...
The reaction of phosphorus pentachloride (PCl 5) with phosphorus pentoxide (P 4 O 10). 6 PCl 5 + P 4 O 10 → 10 POCl 3. The reaction can be simplified by chlorinating a mixture of PCl 3 and P 4 O 10, generating the PCl 5 in situ. The reaction of phosphorus pentachloride with boric acid or oxalic acid: [12] 3 PCl 5 + 2 B(OH) 3 → 3 POCl 3 + B ...
Hexachlorophosphazene is an inorganic compound with the chemical formula (N P Cl 2) 3.The molecule has a cyclic, unsaturated backbone consisting of alternating phosphorus and nitrogen atoms, and can be viewed as a trimer of the hypothetical compound N≡PCl 2 (phosphazyl dichloride).
It appears as a colorless gas with a disagreeable odor, and it turns into a liquid at -8 °C. Phosphorus trifluorodichloride is formed by mixing phosphorus trifluoride with chlorine PF 3 + Cl 2 → PF 3 Cl 2 [2] The P-F bond length is 1.546 Å for equatorial position and 1.593 for the axial position and the P-Cl bond length is 2.004 Å.
