Solvay has developed a shortstop inhibitor designed to protect against runaway polymerization of acrylic and methacrylic acids, esters and other monomers in bulk storage facilities, transportation tanks and containers.
According to the company, runaway polymerization can be hazardous if the reaction becomes uncontrollable and the heat it produces leads to a fire, an explosion, or a rupture of closed storage and transport containers.
Phenothiazine LVT 2330 comprises a 30% active liquid solution of PTZ dissolved into Rhodiasolv Polarclean HSP1 solvent and was developed as an alternative to the use of N-Methyl-2-pyrrolidone (NMP) which is considered a substance of very high concern (SVHC) under REACH regulations, according to Dave Vanzin, technical service manager at Solvay.
The inhibitor is safer to handle than NMP containing solutions and it also has a lower freezing point. The active PTZ concentration of deployment and storage of in both large and small installations, the company said.
