Process for the preparation of cis- AND trans-3,7-Dimethyl 2,6-Octadiene-1-OL from crude sulphated turpentine streamSathikge, Ndavheleseni David January 2008 (has links)
As part of CSIR Biosciences’ interest in aroma chemicals, the processing of crude sulphated turpentine (CST) into high value aroma products was investigated. The primary target product, linalool, was obtained from a mixture of α- and β-pinene in four steps. It can be transformed into a wide range of high value added aroma chemicals. Isomerisation of linalool in the presence of a transition metal catalyst furnishes geraniol and nerol. The scientific work described in this report was part of a bigger project aimed at developing innovative processes to manufacture aroma, flavour & fragrance chemicals through beneficiation of industrial waste streams and other raw materials, available locally from the Forestry, Paper & Pulp industries. The evaluation of a process for the preparation of precursor aroma, flavour & fragrance compounds, in particular geraniol and nerol, from locally available raw materials and industrial waste streams, was investigated. Preparation of geraniol and nerol from linalool (ex α-pinene stream) was investigated using acids or organometallic complexes as catalysts for the corresponding isomerisation reaction. The investigation was conducted in an effort to find a less costly process utilising milder conditions than via the conventional cleavage of β-pinene to myrcene under extreme pyrolysis conditions (>650°C). The transformation of linalool to geraniol/nerol using mineral acids was found to be dominated by secondary reactions such as dehydration and cyclisation, resulting in poor product selectivities and yields. On the other hand, organometallic complexes, in particular vanadium-based complexes (e.g. (OV(OBu)3) produced satisfactory results in the preliminary assessment (conversion of 79.8 percent and selectivity of 98.3 percent). A set of statistically designed experiments was carried out on the (VO(BuO)3 + [(Bu)4N+]OH¯) catalyst system where three variables were tested, i.e. substrate concentration, temperature, and catalyst loading. The selected model for conversion was significant with the “Probability > F” being < 0.0001. The most important contributing variable to the model for conversion was temperature i.e. 83.9 percent. Temperature was still the most important variable for the selectivity response at 65.0 percent contribution level. The response surface generated for the selectivity response was flat indicating a robust method within the parameter range selected.

The demand for British Columbia kraft pulpSuderman, Henry Leonard January 1969 (has links)
The major objective of this study was to determine the outlook of the British Columbia kraft pulp industry for the period 1969 - 1974.
To attain this objective and develop the necessary perspective, the global economy and particularly world trade developments were studied. An historical analysis of world economic variables was made and then, where possible, projections
into the future made. From these studies, specific applications to the British Columbia industry were given.
Consequently, the approach of this study was to begin with general global considerations and then proceed to more specific items pertaining to the British Columbia industry. The global demand trends for kraft pulp were obtained by studying the major kraft pulp consuming areas individually. Other kraft pulp producing areas of the world were analyzed to see what portion of potential demand they would be able to supply on competitive terms with British Columbia.
As the perspective of the study narrowed, it focused on Canada. This country's historic economic and future potential
were analyzed in detail. Recent rapid growth trends were noted and their expansionary effect on British Columbia's economy noted.
This study revealed that previous forecasters generally understated future economic growth, particularly in the area
of world trade. Consequently, a more liberal attitude was adopted in this analysis. On the basis of future reductions in tariffs, particularly the Kennedy Round cuts in the projection
period, the mood of this forecast is one of optimism. Buoyant economic conditions are projected based on premises that state no abrupt changes in world affairs should be expected
in the next five years.
Global kraft pulp demand is expected to grow at least at the same rate as the world GNP growth. The growth rate in economic output has not been too much alike for all countries
and consequently the average global GNP growth has given only a rough indication of kraft pulp consumption. Disproportionate GNP growth in the countries is forecast for the next five years. The industrialized countries will continue to grow faster than the less-developed countries.
Most of the growth in kraft pulp demand will occur in the industrialized countries, of which the most promising areas are in Europe and Japan. Because the traditional sources for European markets are approaching their raw material
limits, substitution from abroad should occur, consequently
the demand for British Columbia kraft pulp should increase at a faster rate than overall global demand.
The overall growth rate for British Columbia kraft pulp is expected to continue close to its historic average annual rate of 16%. The growth in British Columbia however
has characteristically run in cycles and the secondary trend has been accentuated by industry moods of optimism and pessimism.
In the last two years pessimism resulting from over-supply has tempered the overall general growth and a trough in the cyclical pattern is forecast for 1970 or 1971. The market is currently firming; consequently construction and expansion of mills is expected to accelerate and a peak in capacity growth should occur in the latter portion of the five-year projection period. / Business, Sauder School of / Graduate
