Kleurstof Organisch Tussenproduct Ftaalzuur CAS 88-99-3 Polyesterhars Weekmaker
Inleiding:
Kleurloze vlokkige kristallen. Smeltpunt 234℃ (ftaalanhydride wordt gegenereerd bij verhitting tot boven 200℃), relatieve dichtheid 1,593. Oplosbaar in methanol en ethanol, enigszins oplosbaar in water en onoplosbaar in chloroform.
Gebruik:
Gebruikt in synthetische harsen, synthetische vezels en medicijnen. Aangezien ftaalzuur en ftaalanhydride vergelijkbare chemische eigenschappen hebben, wordt ftaalanhydride vaak direct in de industrie geproduceerd. In toepassingen kan ftaalanhydride in plaats van ftaalzuur worden gebruikt. De orale LD50 voor ratten is 7,9 g/kg. Gebruikt bij de productie van kleurstoffen, polyesterharsen, polyester, medicijnen en weekmakers. Bereid standaardoplossingen als alkaliteitstandaarden. Verifieer kobalt, koper, germanium, kwik, nikkel, kalium, strontium en zink, en bepaal kobalt, jodaat en lood. Organische synthese.
