Heat treatment is an approved Quarantine treatment under international standard for phytosanitary measures (ISPM-15) and it is an alternative to Methyl bromide fumigation treatment for wood packaging material of the export consignment. "Heat Treatment vs. Fumigation" HT is an eco-friendly method with least detrimental affect on the environment‚ especially during

ester and there are two esters that are very close in molar mass‚ methyl acetate and ethyl formate. The methyl acetate and the ethyl formate both have a molar mass of 74.08 g/mol [5][6]. The last step is to distinguish between the two. Both methyl acetate and ethyl formate are described as having a “fruity odour”‚ relatively close boiling points and the same colourless appearance [5][6]. However‚ there is one source that says that methyl acetate has a “characteristically pleasant smell reminiscent of

PRODUCTION OF BIODIESEL FROM KARANJA OIL BY TRANSESTERIFICATION INTRODUCTION Majority of the worlds energy needs are supplied through petrochemical sources‚ coal and natural gases‚ with the exception of hydroelectricity and nuclear energy. All these sources are finite and at current rate of usage these will be consumed shortly. The high energy demand in the industrialized world as well as in the domestic sector and pollution problems caused due to the widespread use of fossil fuels make it

William son Eth er Synth esis Introduction In this reaction‚ an alcohol is deprotonated to form a good nucleophile‚ which then attacks the electrophile methyl iodide to form an ether. Tetrabutylammonium bromide‚ a phase transfer catalyst‚ is used to carry ions back and forth between the organic phase and the aqueous phase.
