Synthesis of a novel flame retardant based on DOPO
An intumescent flame retardant (DOPO-DAM) containing phosphorus and nitrogen was synthesized via a two-step process and then, it was incorporated into waterborne polyurethane to serve as a reactive flame retardant for preparing flame-retarded WPU (FR-WPU). The chemical structures of DOPO-DAM and FR-WPU were confirm

An overview of some recent advances in DOPO-derivatives
These DOPO-derivatives are used as flame retardants mainly in epoxy resins [3], [5], [11], [12], [13], [15], for applications in adhesives, composites, printed wiring boards and others [17]. As some halogenated flame retardants have been found to be toxic, the research on halogen-free flame retardants is gaining more and more importance [18].
Flame retardant-DOPO - ChemBK
Introduction. 9,10-dihydro -9-oxa -10-phosphazene -10-oxide is also called 9,10-dihydro -9-oxa -10-phosphazene -10-oxide (DOPO), which is an important new reactive phosphorus-containing flame retardant. The flame retardants synthesized by DOPO and its derivatives have the characteristics of high efficiency, halogen-free, smokeless, non-toxic
- Is Dopo a flame retardant?
- Synthesis of organophosphorus compounds based on 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and its application as flame retardant have created much attention in the flame retardant community. Various chemical reactions and synthetic approaches are followed to develop numerous derivatives of DOPO.

- Can disubstituted p -hydroquinone be used as a flame retardant?
- Proposed mechanism for synthesis of disubstituted p -hydroquinone. Compound 2 is a reactive monomer, Owing to the diol functionality. Therefore, it could be incorporated into the molecular backbone of polymers for flame retardant application.
- Are Dopo-derivatives a suitable alternative to halogenated flame retardants?
- DOPO-derivatives are considered as suitable alternative to halogenated flame retardants because of their versatile flame extinguishing behavior in gas phase and condensed phase . Despite a growing interest in DOPO-derivatives as flame retardants , there exist no comprehensive review on their synthesis and application.
- Which phosphorous phosphate ester is best for flame retarding?
- As phosphorous organic its performance are chemically linked to resin matrix and is better than other phosphate esters in flame retarding due to the P-C bond. Tests show that EVERFOS DOPO has a less smoke density besides no corrosive gases for molders or extruders, is also suitable for high TG applications for resin and thermoplasts.
- Can Atherton-Todd reaction be used as a flame retardant?
- They have been reported as effective flame retardants for application in polyurethane foams and engineering plastics . Döring and coworkers have also used Atherton–Todd reaction as versatile tool to synthesize some new DOPO-compounds (Fig. 8) .
