Abstract:
     A process for dechlorinating the bleached shellac features that the bleached shellac is irradiated by infrared ray with 650 mm of wavelength and 100000 Luxes of intensity to quickly decompose bleaching agent NaClo to educe out Cl2. Its advantages are high effect Cl (content is lower than 0.8%) and long storage time of product (more than 2 years).
