Abstract

The present invention provides triallyl isocyanurate comprising a less amount of corrosive substances by identifying the corrosive substances among impurities included in the triallyl isocyanurate. Triallyl isocyanurate of the present invention comprises an organic chlorine compound represented by the following general formula (I) in an amount of not more than 100 ppm: wherein R 1 and R 2 are respectively a chlorine atom or an allyoxy group with the proviso that at least one of R 1 and R 2 is a chlorine atom.

Claims (15)

1. Triallyl isocyanurate containing an organic chlorine compound represented by the following general formula (I) as an impurity in an amount of not more than 100 ppm:

wherein R 1 and R 2 are independently a chlorine atom or an allyoxy group with the proviso that at least one of R 1 and R 2 is a chlorine atom.

2. Triallyl isocyanurate according to claim 1 , wherein the triallyl isocyanurate is produced by subjecting triallyl cyanurate to rearrangement reaction.

3. Triallyl cyanurate comprising organic chlorine compounds represented by the following general formulae (I) and (II) in a total amount of not more than 800 ppm:

wherein R 1 and R 2 are independently a chlorine atom or an allyoxy group with the proviso that at least one of R 1 and R 2 is a chlorine atom.

4. The process for producing the triallyl isocyanurate as defined in claim 1 , comprising the step of subjecting the triallyl cyanurate to rearrangement reaction.

5. The process for producing the triallyl isocyanurate according to claim 4 , wherein the triallyl cyanurate is produced by reaction between cyanuric chloride and allyl alcohol.

6. A process for producing triallyl isocyanurate, comprising the steps of:

reacting cyanuric chloride with allyl alcohol to obtain triallyl cyanurate;

subjecting the thus obtained triallyl cyanurate to stirring treatment in a strong base aqueous solution having a concentration of 0.5 to 10% by weight at a temperature of 50 to 80° C. for 0.5 to 10 hours; and

subjecting the thus treated triallyl cyanurate to rearrangement reaction.

7. Triallyl cyanurate according to claim 1 , wherein the amount of organic chlorine compound represented by the general formula (I) is not more than 50 ppm.

8. Triallyl cyanurate according to claim 1 , wherein the amount of organic chlorine compound represented by the general formula (I) is not more than 30 ppm.

9. Triallyl cyanurate according to claim 3 , wherein the total amount of organic chlorine compounds represented by the general formulae (I) and (II) is not more than 500 ppm.

10. Triallyl cyanurate according to claim 3 , wherein the total amount of organic chlorine compounds represented by the general formulae (I) and (II) is not more than 100 ppm.
