STUDIES ON THE PULPING AND CHEMICAL CONSTITUENTS OF PINUS CARIBAEA

Abstract

Pinus is genera of plants belonging to the family Pinaceae of the order coniferales and of class Gymnosperms. The genus pine, being a source of resins, turpenes and paper pulp is very important amongst the conifers in India. Pinus caribaea grows in Bahama Islands, Western Cuba and Nicaragua, it is mainly distributed in Islands of Caribean and costal of Central America. The altitude range of Pinus caribaea is being taken from sea level to 300 m. Pinus caribaea is a fast growing exotic pine species in comparision to other pines species. Studies have thus been carried out to cover the pulping and chemical constituents of Pinus caribaea. On reviewing the past literature, it is evident that no systematic work is reported in literature on the chemistry of Pinus caribaea and the reactions occuring on the chemical constituents during pulping so far. This study will not only give the chemical composition of the wood but will also help in better under standing its reaction during pulping and bleaching for different grade of pulps used for various types of papers. This study will also help in using alternative raw materials to the paper industry......
