There\nis not a listing for \"Ethyl acrylate, inhibited\". In Appendix A to 172.101, Ethyl acrylate is listed as\nhazardous substance using two chemical names: Ethyl acrylate or 2-Propenoic acid, ethyl ester.\nBoth hazardous substance listings have a RQ of 1000 Ibs. When you look in Appendix B to\nhowever, there is a marine pollutant under the name \"Ethyl propenoate, inhibited\".\n172.101, there are no listings under the names Ethyl acrylate or 2-Propenoic acid, ethyl ester;\nthe name \"Ethyl propenoate\" is a synonym for Ethyl acrylate. The only difference is \"inhibited\" vs.\nThe problem is\n\"stabilized\".\nShould Ethyl acrylate in bulk containers be shipped as a marine pollutant due to the marine\npollutant listing \"Ethyl propenoate, inhibited\"?\nAny assistance in clarifying this issue is appreciated.\nKind regards,\nShinyd Amall.\nProduct Safety Specialist\nSheryl Small\nSasol North America Inc.\nHouston, TX 77079\n900 Threadneedle, Ste. 100\n(281) 368-1552 fax\n(281) 588-3492 phone\nsheryl.small@us.sasol.com\nG00 Threadpeedie Suite 100\nSasol North America Inc.\nTelephone (41) 281 588 3000\nHouston Texas 77079\nwww.sasolnorthamerica.com","truncated":false,"body_characters":4026}
