Sintesis Xilitol dengan proses elektroreduksi xilosa.

Abstract

Proses produksi xilitol secara elektrokatalitik dari D-xilosa dalam larutan sodium sulfat menggunakan timbal amalgam telah dipelajari. Produk yang dihasilkan ditentukan memakai HPLC. Katoda timbal amalgam digunakan untuk mempertinggi rendemen relatif Faraday pada produksi xilitol melalui reaksi hidrogenasi katalitik heterogen dengan H. Pada densitas anus rendah dan konsentrasi D-xilosa yang tinggi, rendemen relatif Faraday meningkat. Tidak banyak perbedaan jumlah xilitol yang dihasilkan akibat variasi pH. Produk samping dalam jumlah yang sedikit juga dihasilkan. A electrocatalytic process of production of xylitol from D-xylose in sodium sulphat solution on amalgamated lead cathode has been studied. The produtcs were determined by HPLC. An amalgamated lead cathode has been employed to enhance Faradaic yield in xylitol production by heterogenous catalyticreaction of hydrogenation with H. At low current densities and high concentration of D-xylose, the Faradayc yield of xylitol was markedly increased. There were not any differences of xylitol yield that caused of variation of pH. Side produtcs were also formed in low yield. V This document is Undip Institutional Repository Collection.
