The Comparative Nucleophilicity of Naphthoxide Derivatives in Reactions with a Fast-Red TR Dye  Cheryl M. Mascarenhas
In this experiment, organic chemistry students perform reactions between three naphthyl acetate derivatives and the diazonium salt Fast-Red TR. Students discover under what conditions the hydrolysis and electrophilic aromatic substitution is fastest and slowest, allowing them to conclude that latter, rather than the former, is rate-limiting.

Separation of the Carotenoid Bixin from Annatto Seeds Using Thin-Layer and Column Chromatography  James V. McCullagh and Nicholas Ramos
In this experiment the carotenoid bixin is isolated from annatto seeds using column chromatography and then analyzed by UVvis and IR spectroscopy. The procedure has several advantages over previous pigment separation experiments.

Annatto Polymeric Microparticles: Natural Product Encapsulation by the Emulsion–Solvent Evaporation Method  Zaine Teixeira, Nelson Durán, and Silvia S. Guterres
In this experiment, extract from annatto seeds is microencapsulated in poly(3-hydroxybutyrate-co-3-hydroxyvalerate) by the emulsionsolvent evaporation method. Encapsulation delays degradation and promotes the sustained release of bixin, an extract useful in the cosmetic and food industries.

Spectrophotometer, Scanning UV-Visible (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Spectrophotometer, Scanning UV/Visible: this is a resource in the collection "ChemPages Laboratory Resources". A scanning ultraviolet/visible (UV/Vis) spectrophotometer operates on the same principles as a Spectronic 20?. They both can be used for qualitative and quantitative analysis. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.

Spectrometer, Spectronic 20 (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Spectrometer, Spectronic 20?: this is a resource in the collection "ChemPages Laboratory Resources". The Spectronic 20? is used to measure the absorbance (or transmittance) of solutions. A Spectronic 20? is capable of measuring % transmittance and absorbance over the range of 340 to 950 nm (the range 600 to 950 nm requires a special infrared filter and a different lamp). The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
