The purpose of this book is to present the latest concepts in wood chemistry and wood compos ites as understood by the various authors who have written the chapters. I thank them for their time and effort in the preparation of this book. The book is an update of two earlier books, Chemistry of Solid Wood, Advances in Chemistry Series, 207, American Chemical Society, Washington, DC. 1984, which is long out of print and the first edition of this CRC handbook published in 2005. - Ushbu kitobning maqsadi yog'och kimyosi va yog'och kompozitsiyalari bo'yicha so'nggi tushunchalarni boblarni yozgan turli mualliflar tushunadigan tarzda taqdim etishdir. Ushbu kitobni tayyorlashda vaqt va kuch sarflaganlari uchun ularga minnatdorchilik bildiraman. Kitob avvalgi ikki kitobning yangilanishidir, “Qattiq yogʻoch kimyosi”, “Kimyodagi yutuqlar” seriyasi, 207, Amerika kimyo jamiyati, Vashington, Kolumbiya okrugi. 1984 yil, u uzoq vaqtdan beri chop etilmagan va 2005 yilda nashr etilgan ushbu CRC qo'llanmasining birinchi nashri.
