Yellow powder

1. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is a yellow powder, also called triphenylcarbenium tetrakis(pentafluorophenyl)borate, used as a borate cocatalyst for olefin polymerization.
2. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 serves as an activator for neutral group 4 metallocenes by abstracting an alkyl group and generating the cationic catalyst.
3. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is employed in propylene and other polyolefin processes, including commercial grades such as PF-41 at about 97% purity or higher.
4. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is supplied for laboratory and industrial polymerization work, with formula C43H15BF20, a molecular weight of about 922.37, and a melting range of about 174–185°C.

1. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 should be stored in a cool, dry, well-ventilated place, with the container kept tightly closed under an inert atmosphere.
2. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is moisture sensitive and air sensitive, and it should be kept away from water and strong oxidizing agents; some suppliers specify 2–8°C under nitrogen or argon.
3. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 has no single published shelf life on the safety data sheets reviewed, and catalytic grades are kept dry to a moisture limit of about 0.5%, so the batch certificate should be followed.

1. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is harmful if swallowed, in contact with skin, or if inhaled (H302, H312, H332) on the common supplier safety data sheets.
2. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 causes skin irritation (H315), causes serious eye irritation (H319), and may cause respiratory irritation (H335).
3. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is also classified on a European safety data sheet as very toxic to aquatic life with long-lasting effects (H410), while an older laboratory sheet assigns severe skin burns and eye damage (H314, H318).
4. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 may form combustible dust concentrations in air and is stored as a combustible solid; the reviewed sheets do not give a closed-cup flash point.

1. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is not safe for uncontrolled handling because it is harmful by ingestion, skin contact, and inhalation, and it irritates the skin, eyes, and respiratory tract.
2. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 requires protective gloves, safety goggles, and protective clothing in a well-ventilated area or fume hood, and dust should not be breathed or dispersed.
3. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 is labeled Warning with GHS07 on the principal supplier sheets, with GHS09 where the aquatic classification is applied, and Danger with GHS05 on the older corrosive classification.
4. Trityl tetrakis(pentafluorophenyl)borate CAS 136040-19-2 must not be released into drains or the environment, and spills should be collected without creating a dust cloud and disposed of as hazardous waste.
