I suspected that the peroxide present in the allyl alcohol reacted with my catalyst used in ppm scale for the reaction. I did the distillation in the presence of K2CO3 but could not solve the problem.
Dear Ramesh, in my experience, 100-200ppm of BHT should take care of your peroxide problem, if this is the problem:

As addition to quality answers of colleques (BHT to prevent and phosphines/phosphites for destruction of peroxides) :
distill allyl alcohol in argon atmosphere
Dear Andrei,
Could you please suggest me the reference for it if possible.
http://en.wikipedia.org/wiki/Organic_peroxide - for common answers about tendence to allyl peroxidation and peroxide reaction with phosphites
Check citation from Google search for terms 'phosphites+ peroxides +reaction'
About argon atmosphere to prevent peroxide formation - no specific literature, exluding known from common synthetic laboratory manuals. It is simply replacing of oxygen by heavier gas (by argon; cyclo-C4F8 or SF6 - if available)
Allyl alcohol (H2C=CH-CH2OH) can form peroxides in the sites of the 2 functional groups. To wash the peroxides away, I suggest a very simple method (to try ). Add to allyl alcohol, small amount of aqueous ferrous sulfate solution & shake gently in a flask. If 2 layers form, discard the smaller layer . Apply efficient fractional distillation to separate the alcohol since it boils at 97 oC. Place a drying agent in the receiving flask & collect an amount nearly similar to what you started with.Decant allyl alcohol carefully. I wish you success.
