| titleOfInvention | Preparation method for dissolving pulp of monterey pine of needlebush |
| abstract | The invention discloses a preparation method for dissolving pulp of monterey pine of needlebush and provides a preparation method, wherein in the pre-hydrolyzing stage, mannose is maximally dissolved to recover hemicellulose source sugar to the maximum extent, in the decocting stage, a pulp yield is higher without Na2S, and the content of cellulose is high. The preparation method comprises the following steps of: placing monterey pine sawdust extracted by a benzene and alcohol mixed organic solvent in a closed decocting kettle; pre-hydrolyzing for 1.5-2 hours at 140 DEG C with liquor ratio of 7:1(L/g) in a sulphurous decocting liquid, wherein the basic group used is Mg(OH)2; placing residue obtained by pre-hydrolysis to the decocting kettle, adding 29-33% of NaOH liquid with liquor ratio of 3.5:1(L/g), screwing and sealing, and placing for 24 hours at room temperature; and then, heating the decocting kettle on an oil bath with the vibrating function to decoct and delignify to obtain the dissolving pulp of monterey pine of needlebush. According to the method, the yield of dissolving pulp and glucose content in slurry are higher without adding Na2S. |
