SYNTHESIS OF SPHERICAL SILICA PARTICLES WITH 3-MERCAPTOPROPYL GROUPS IN THEIR SURFACE LAYER [PDF]
Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2012 Spherical silica particles were synthesized by modified Stöber method using tetraethoxysilane and 3- mercaptopropyltrimethoxysilane (MPTMS). It was shown that their size (500-760 nm) depends on the nature of the catalyst used in the prehydrolysis of ...

Continuous Prehydrolysis in Sulfate Process for Preparation of Dissolving Pulp
JAPAN TAPPI JOURNAL, 1959 In the preparation of dissolving sulfate pulp by the conventional batch system, the digestion is about three cycles per day, and the acid treatment (prehydrolysis) and alkaline cooking (sulfate cooking) are both carried out in a single digester. This process could be improved markedly by separating the prehydrolysis process from the alkaline cooking ...

Novel Lab‐Scale System for Lyocell Fiber Manufacturing
Journal of Polymer Science, Volume 63, Issue 16, Page 3358-3378, 15 August 2025.ABSTRACT Lyocell man‐made cellulosic fibers (L‐MMCFs) are typically produced from wood sources, but sustainability efforts are driving interest in agricultural biomass feedstocks. This study presents a lab‐scale system for evaluating feedstock viability and processing conditions using a rotary evaporator, syringe pump, and microreactor vessel.

Influence of xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]
BioResources, 2012 Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...
