Abstract
A process of cleaning a reactor includes providing an alcohol-containing material to the reactor; and providing a metathesis catalyst to the reactor. The reactor contains a high molecular weight polymer gel and an organoaluminum material. The alcohol-containing material is not an alkyl tartrate and may be selected from triisopropanolamine, 4-tert-butylcatechol, isopropanol, and phenol formaldehyde resins.
Claims15
A process of cleaning a reactor containing a polymer gel and an organoaluminum material, the process comprising:
- providing an alcohol-containing material to the reactor in an amount of from about 1 to about 1000 mol per mol of the organoaluminum material;
- and
- providing a metathesis catalyst to the reactor;
- wherein the alcohol-containing material is not an alkyl tartrate.
A process of cleaning a reactor containing a polymer gel and an organoaluminum material, the process comprising:
- providing an alcohol-containing material to the reactor;
- and
- providing a metathesis catalyst to the reactor;
- wherein the alcohol-containing material is not an alkyl tartrate, wherein the alcohol-containing material is selected from a polymer or a catechol compound.
A polymerization and reactor cleaning process comprising in sequence:
- polymerizing at least one monomer in the presence of a catalyst system comprising an organoaluminum compound;
- providing an alcohol-containing material to the reactor, wherein the alcohol-containing material is provided to the reactor in an amount of from about 1 to about 1000 mol per mol of organoaluminum material in the reactor;
- providing a ruthenium-containing metathesis catalyst to the reactor;
- and
- recovering a polymer from the reactor.
