Unit I: 

Laboratory Safety Measures                                  

MSDS, identification, verification and segregation of laboratory waste, disposal of waste in sanitary sewer system, incineration and transportation of hazardous chemicals. Flammable solvents, fire hazards in chemical laboratory.

 

Basic techniques Involved in Synthetic Organic Chemistry

  • Different types of glasswares.
  • Filtration.
  • Distillation (distillation at atmospheric pressure, steam distillation, fractional distillation and distillation at reduced pressure).
  • Recrystallization and melting point correction.
  • Use of decolorizing carbon.
  • Thin layer chromatography.

Qualitative Analysis

Separation, purification and identification of components of a mixture of two organic compounds (one liquid and one solid or two solids) using TLC for checking the purity of separated compounds.

 

Quantitative Analysis

  • Determination of the percentage and number of hydroxyl groups in an organic compound by acetylation method.
  • Estimation of amines/phenols using bromate bromide solution.
  • Determination of iodine number and saponification value of an oil sample.

Demonstration Exercise

  • Estimation of sulphur by messenger or fusion method.
  • Estimation of nitrogen by Kjeldahl’s method.
