| Materials which react with (“scavenge”) sulfur compounds, such as hydrogen sulfide and mercaptans, are used to limit sulfur-induced corrosion. Filters and protective coatings including these materials, described broadly as polyhexahydrotriazines (PHT) and polyhemiaminals (PHA), are disclosed. Methods of using these materials to prevent corrosion are described. PHT and PHA materials have excellent thermal and mechanical properties for many applications as coatings and filtration media. Specifically, PHT and PHA materials react with sulfur compounds in such a manner as to incorporate sulfur atoms into the polymeric matrix, thus sequestering the sulfur atoms and allowing removal from fluids such as crude oil, natural gas, hydrocarbon combustion exhaust gases, sulfur polluted air and water. A coating PHT or PHA material on a component to be protected similarly reacts with sulfur compounds prior to sulfur being able to penetrate to the component. | ||||||

| 40 | Process for preparing filter material | US907017 | 1978-05-17 | US4171390A | 1979-10-16 | Karl Hilterhaus; Franz G. Reuter |
| A process of producing a porous polyurethane resin filter material. A first solution containing an NCO-adduct dissolved in a highly polar organic solvent is admixed into a second solution containing a highly polar organic solvent and at least one hydrazine hydrate, carbodihydrazide, piperazine and 1,4-diaminopiperazine. The first solution is admixed into the second solution over an extended period of time during which time the viscosity of the admixture is monitored and during which time the NCO pre-adduct and the hydrazine (or the like) react to form a polyurethane reaction product. During this time, the viscosity of the admixture increases. Admixture is continued with monitoring of the viscosity of the admixture until a point is reached at which the addition of even the minutest amount of the first solution into the admixture would result in instantaneous gelling thereof. At this point, the solids content of the final admixture is between 15 and 35% by weight.The final admixture, which is castable for at least 24 hours, is coated on a textile reinforcing material and the coated material is introduced into a coagulating bath of water with no additives to form a polyurethane sheet structure which is dried to form the porous polyurethane resin filter material in accordance with the invention. | ||||||
