identify the unknowns by analyzing the physical properties on IR and NMR spectrums. The neutral solid was purified through recrystallization and the melting point range was determined to be 47.5oC to 48.9oC. The basic liquid was purified with simple distillation and the boiling point of 135oC was concluded. Through the analysis of IR spectrum of each unknown the structures for each unknowns were devised. An important peak for the solid unknown D was 1655.71 cm-1 (Ketone) and the peaks that were important

An attempt has been made to prepare a 100% herbal product based on Citronella leaf remains which is left out and of no use after steam distillation. It is cheap‚ effective and environment friendly. It is a first and preliminary work based on formulating and evaluating herbal mosquito repellent cakes using natural binders such as neem powder‚ potato starch‚ corn starch‚ coconut shell powder

CHAPTER ONE 1.0 INTRODUCTION Starch is one of the most abundant substances in nature‚ a renewable and almost unlimited resource. Starch is produced from grain or root crops. It is mainly used as food‚ but is also readily converted chemically‚ physically and biologically into many useful products to date; starch is used to produce such diverse products as food‚ paper‚ textiles‚ adhesives‚ beverages; confectioning‚ pharmaceuticals‚ and building materials. Cassava starch has many remarkable characteristics

is energy-intensive. To save energy‚ superheated steam (SS) could be used for drying spent grains. The circulation of SS in the closed-loop drying system can reduce the energy wastage that occurs with hot-air drying. Also‚ the exhaust steam produced from the evaporation of moisture from the wet product can be used in other operations in the distilleries‚ such as cooking raw materials‚ stripping and rectifying distillation of ethanol‚ and concentrating residual stillage.
