Time, temperature and amount of distilled water effects on the purity and yield of bis (2-hydroxyethyl) terephthalate purification system

Polyethylene terephthalate (PET) bottle is one of the common plastic wastes existed in the municipal solid waste in Malaysia. One alternative to solve the abundant of PET wastes is chemical recycling of the wastes to produce a value added product. This technology not only can decrease the PET wastes...
