1. Propri\u00e9t\u00e9 du produit<\/b><\/strong><\/h3>\n

Le 1,4-butanediol est un liquide visqueux incolore avec une l\u00e9g\u00e8re odeur. Il est miscible avec l'eau et est \u00e9galement soluble dans la plupart des solvants organiques. Il a un point d'\u00e9bullition de 228\u00b0C et un point de fusion d'environ 20\u00b0C\u3002Il peut r\u00e9agir avec des oxydants puissants et est g\u00e9n\u00e9ralement stable dans des conditions normales\u3002.<\/p>\n

3. Champ d'application et utilisation<\/b><\/strong><\/h3>\n

Le 1,4-butanediol est largement utilis\u00e9 comme solvant dans les industries de la peinture, de l'encre et du rev\u00eatement. Il sert \u00e9galement d'interm\u00e9diaire dans la production de polyamides, de polyur\u00e9thanes et d'\u00e9lastom\u00e8res. En outre, il est utilis\u00e9 dans la synth\u00e8se de produits pharmaceutiques et comme humectant dans les cosm\u00e9tiques. C'est un ingr\u00e9dient cl\u00e9 dans la production de\u03b3-Butyrolactone et de N-M\u00e9thyl-2-pyrrolidone\u3002.<\/p>\n

4. Emballage et stockage<\/b><\/strong><\/h3>\n

Le 1,4-butanediol est g\u00e9n\u00e9ralement conditionn\u00e9 dans des sacs en polypropyl\u00e8ne d'un poids net de 25 kg avec une doublure en film poly\u00e9thyl\u00e8ne\u3002Il doit \u00eatre stock\u00e9 dans un endroit frais et sec, \u00e0 l'abri des sources de chaleur et de la lumi\u00e8re directe du soleil, afin d'\u00e9viter l'\u00e9vaporation et la d\u00e9gradation. La zone de stockage doit \u00eatre bien ventil\u00e9e pour minimiser l'accumulation de vapeurs. Le produit doit \u00eatre tenu \u00e0 l'\u00e9cart des agents oxydants forts et des acides. Des mesures de s\u00e9curit\u00e9 appropri\u00e9es doivent \u00eatre prises pour \u00e9viter toute contamination et garantir une manipulation s\u00fbre\u3002.<\/p>","protected":false},"excerpt":{"rendered":"
