The carbonyl index is calculated as the ratio of the intensity (or total area) of the 1715 cm(-1) carbonyl peak in the FTIR spectrum to a reference peak such as 1456 cm(-1) or any other nearby strong peak for the particular PP material being analyzed.
Carbonyl index is a measure of oxidative degradation in oils and fats, specifically the concentration of carbonyl compounds formed due to oxidation. It is often used as an indicator of rancidity and deterioration in food products. A higher carbonyl index value indicates greater oxidative damage and lower product quality.
You can determine if a plastic item is made of polyethylene or polypropylene by looking for the recycling symbol on the item. Polyethylene is usually labeled with the number 2 inside the recycling symbol, while polypropylene is labeled with the number 5.

Polypropylene can be dyed using disperse dyes, but the process can be challenging due to the material's low absorbency and resistance to dye penetration. It is recommended to consult with a professional or conduct a small-scale test to determine if the desired dyeing results can be achieved on polypropylene.
An index mineral is used in geology to determine the degree of metamorphism a rock has experienced.

Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Your body weight index is determined by your height and weight. I have attached a link to website that will provide you with a calculator to determine your body weight index: www.living-a-healthy-lifestyle.com/body-mass-index.html
The abbreviation for polypropylene is PP.
Polypropylene is not dissolved in ethanol.
What is a prism and how does it relate to the refractive index? Explain how the refractive index of a prism affects the bending of light. How can you experimentally determine the refractive index of a prism?
The heat index combines air temperature and relative humidity to determine how hot it feels outside.
