, fluorosulfonic acid, amidosulfonic acid, free sulfur trioxide and its complexes, halogen derivatives of sulfuric acid, etc.
18) was different from ours; the deformed specimens were first stained and fixed in chlorosulfonic acid
and ultrathinsections were then cut from the samples for the TEM experiments.
The current research shows that we have a true solvent for nanotubes -- chlorosulfonic acid
-- which is what we set out to find when we started this project nine years ago.
Pasquali, primary author Nicholas Parra-Vasquez and their colleagues reported this month in the online journal ACS Nano that chlorosulfonic acid
can dissolve half-millimeter-long nanotubes in solution, a critical step in spinning fibers from ultralong nanotubes.
This stage included the surface modification of sodium montmorillonite nanoparticles by using chlorosulfonic acid
, and carrying out the required tests.
The researchers took advantage of novel cryogenic techniques for electron microscopy that allowed them to directly image the graphene sheets in the chlorosulfonic acid
It had been hoped to use chlorosulfonic acid
for item (f), and sulfur dichloride or monochloride for (g).
The emergency exercise simulated a rail tank car derailment causing the "spill" of chlorosulfonic acid
, a raw material used in Rhodia's Baltimore plant.
For surfactant synthesis, Chlorosulfonic acid
(97%), pyridine (99.
The company's main products include acetic acid, ammonia, urea, methanol, chlorosulfonic acid
, and amino-plastics.
The researchers have reported that chlorosulfonic acid
can dissolve half-millimeter-long nanotubes in solution, a critical step in spinning fibres from ultralong nanotubes.
Fifty milliliter of chlorobenzene was charged into a round-bottomflask equipped with a mechanical shaker and connected to a dropping funnel filled with a stoichiometrical amount of chlorosulfonic acid
