摘　　要：介绍了溶剂法制浆和自催化乙醇法的起源、定义和基本原理,重点论述了乙醇法制浆工艺、蒸煮历程、脱木素机理以及动力学等方面的研究成果,总结了多种木材和非木材原料乙醇法制浆工艺及机理。The origin of organsolv pulping and auto-catalyzed ethanol pulping, and the definition and fundamental ,principal of auto-catalyzed ethanol pulping are introduced. The technology, cooking process, delignitication mechanism and dynamics of auto-catalyzed ethanol pulping are emphasized. Ethanol pulping of various kinds of fibers is studied. It is found that H^＋ consistency plays an important role, bulk and residual delignitication stages are observed for both wood and nonwood fibers, some arguments about delignification mechanism still exist althrough the breaking of a-O-4 ether bond in mild acidic environment is agreed. Achievements on ethanol pulping have been recognized, but some aspects still need to be further studied.
