P-NMR spectra exhibited significant up-field chemical shift changes in the presence of the sulfur mustard and its analogous compound.
The yield of the reaction was 99.9% with the final relative product distribution of 10% for compound I, 20% for compound II, 20% for compound III and 50% for compound IV.

 Carbon Nanotubes Monthly - February 2006 - Patents on Nanotubes Purification
The second method employed a complex treatment involving soaking the nanotube in aromatic hydrocarbon and hydrochloric acid solution, complemented by a cryogenic treatment through liquid nitrogen soaking.
Jeffrey Bahr, Yuemei Yang, Kenneth Mcelrath, Martin Grosboll and Aurelie Mayeux claimed that a material comprising carbon nanotubes, a magnesia support and a catalyst metal can be purified by immersing it in a mixture comprising carbon dioxide and water (applicant: Carbon Nanotechnologies Inc., WO2005056474).
Maurizio Prato and Vasilos Georgakilas were granted a patent for their “purification process of carbon nanotubes”, which used organic functionalization of raw nanotubes, followed by their precipitation and subsequent regeneration of non-functionalized nanotubes by heat treatment (US2005234263).
