Photostability of isosafrole | Bookmark | ||||||
It is recommended to keep isosafrole in an opaque bottle. So what happens if one were to set some isosafrole out in a clear container in direct sunlite. What would happen to the molocule? There must be a reason that it is stored dark. VL_ |

Polymerization | Bookmark | ||||||
I bet it would start to polymerize, and maybe even oxidize. Ultraviolet light will also degrade the methylenedioxy ring, although only minutely if it is pure iso with no impurities. (impurities = "degradation catalysts") PrimoPyro |

Say there is no oxygen available. Why would it polymerize. What exactly is happening. |

The double bond opens, forming a free radical generated by the UV, then this adds to the alkene part of another moleculem, and then it goes on reacting like that. Google for free-radical polymerization. |

I don't think that radical polymerisation takes place. As far as I know allyl- and propenylbenzenes are pretty inert to that kind of reaction. If at all some dimerisation or trimerisation will happen forming some unsymmetrical end product. But I think all that decomposition talk is overrated, I doubt that much decomposition will happen at all (as long as oxygen is kept out). It might change colour and appearance over time, but pretty much all of the saf/iso should survive long storage times under less than favorable conditions. I'm not fat just horizontally disproportionate. |
