New Utilization Possibility of Furfural for the Synthesis of Self‐Extinguishing Polyurethane Resins
A new method for the conversion of furfural into heptane‐1, 4‐diol, 3, 5‐dichloroheptane‐1, 4‐diol as well as 3, 5‐dibromoheptane‐1, 4‐diol is presented, and the possibilities of applying of two last alcohols for the syntheses of self‐extinguishing polyurethane resins are discussed. In addition, a method for the preparation of ethyl 3, 5‐dichloro‐4‐keto‐ and 3, 5‐dibromo‐4‐ketoheptanoate is described.
2,3-Dihalogen-1,4,7-heptantriole als Flammschutzmittel in PUR-HartschaumenKrzysztof Marzec (Eingegangen am 18. Marz 1991) ZUSAMMENFASSUNG:Die Verwendbarkeit der aus 2-Furaldehyd erhaltenen Halogentriole 2,3-Dichlor-und 2,3-Dibrom-I ,4,7-heptantriol als reaktive Flammschutzmittel fur PUR-Hartschaume wurde untersucht. Zur Modifikation der Schaume wurden diese Verbindungen allein und im synergistischen System mit Antimontrioxid verwendet.
SUMMARYThe application of 2,3-dichloro-and 2,3-dibromo-l,4,7-heptanetriol, obtained from 2-furancarboxaldehyde, as reactive flame-retarding agents for rigid polyurethane foams was investigated. For the modification of the foams, these compounds were used alone and with antimony oxide in the synergistic system CI/Sb and Br/Sb.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
