FS/2018 ORGANIC CHEMISTRY I LAB CHEM 226 (2219) Instructor: Terry Bone 120-B Schrenk Hall [email protected] 341-4820 http://www.mst.edu/~tbone 9:00-10:00, Tu-Th, or by appt. Cynthia Bolon 213 Schrenk Hall [email protected] 341-4439 OBJECTIVES: Course objectives are to develop facility with performing laboratory techniques involving the handling of organic chemicals safely and the keeping of proper records of experiments conducted in the laboratory. Crystallization, distillation, extraction and chromatography are emphasized as separation and purification techniques. Melting points, boiling points, and refractive indices are used routinely as measures of purity. Safe handling of chemicals and proper disposal of waste products are priority goals in this course. To help in attaining such goals, the first week of the semester is devoted to SAFETY in the chemistry laboratory. For the remainder of the semester, most of the experiments are conducted on a micro scale.

Isolation and Characterization of a Natural Product: Caffeine
Cerritos Community College Organic Chemistry 211 Laboratory Isolation and Characterization of a Natural Product: Caffeine. O O CH3 N H HN – H3C N O N N O N N P OH H2N N O O N N N N O H3C OH purine 2'-deoxyguanosine caffeine 5'-phosphate In this experiment, the techniques of solid-liquid extraction and liquid-liquid extraction will be used to isolate caffeine from tealeaves. A new purification technique, sublimation, will be used to perform the final purification. Caffeine is a member of the class of natural products called alkaloids, which contain nitrogen. Other members of this class include morphine, mescaline, and strychnine. The strong biological activity of these compounds has led to their thorough investigation by many different disciplines. Caffeine possesses the oxidized skeleton of purine, a relative of which can be found as a constituent of DNA (see above). Caffeine is found in many plants with coffee and tea being the most familiar. A cup of coffee or tea provides a 25- to 100-mg “Dose” of caffeine, which stimulates the central nervous system in a widely exploited manner. From the preceding, it is not surprising that caffeine is soluble in hot water, but it is also soluble in dichloromethane, allowing the following extractive protocol to isolate it. This two-step extractive isolation assures that ionic species remain in the aqueous layer while taking advantage of the swelling that water causes in the tea leaves. Simply extracting the tealeaves with dichloromethane directly is ineffective. The sodium carbonate added to the water during the “steeping” stage is to insure that the caffeine and organic acids are deprotonated. -

Chemistry Lab Course
Chemistry Lab Course Kantonsschule Zürich Nord Tilmann Geldbach 2015/2016 Chemistry Lab 2 Preface The aim of this lab course is that you learn how to conduct simple chemical experiments and how to document these experiments. You should learn to carefully observe and – based on these observations – come up with explanations and hypotheses about what you have seen. During the course you will learn basic lab techniques, the proper use of standard equipment as well as how to handle harmful chemicals. Organisation It is expected that you have studied the lab instructions of the current experiment before the lesson has started. Remaining questions can be clarified before the lab session starts. In most cases you will be working in pairs. You should always take notes on what you are doing and on what can be observed. There is a work sheet for most of the experiments. You should return this work sheet at the end of the lab session or unasked in the next theory lesson at the latest. These work sheets will be graded with bonus points. The lab should be fun! Therefore make an effort to create an atmosphere that is pleasant both to you and your classmates. You should help each other both during the experiments and during clean-up. Not all substances that are used in the lab are harmless. Pay attention to the safety instructions below and on the sheets of the respective experiment. Safety There are essentially three ways in which a chemical substance may enter your body: by oral uptake, by inhalation or by absorption through the skin. -

Pre-requisite Module 6: Safety at HIV Rapid Testing Site Modules Module 8: Blood Collection – Fingerprick Module 13: EQA Learning At the end of this module, you will be able to: Objectives Collect dried blood spots (DBS) Package and store DBS in a way to maintain specimen integrity Maintain DBS records Distinguish between valid and invalid DBS Content Outline Required supplies How to collect and dry DBS How to package and store DBS Valid and invalid DBS Hands-on practice Handout Example Specimen Transfer Log for Re-Testing Notes on Customization Module 14: EQA – Dried Blood Spots 1 Participant Manual 2005 What Is a Dried Dried Blood Spots (DBS) are whole blood collected on filter paper Blood Spot and dried. They are made directly from the client’s whole blood. (DBS)? DBS are used for re-testing at a reference laboratory, which may be part of your country’s External Quality Assessment plan. Testing site results are compared to reference laboratory results. DBS samples are useful for re-testing as they are easy to collect, store, and transport. EQA Re-testing Remember…Two types of specimens may be collected at the site for referral to a reference lab for re-testing: serum/plasma or dried blood spots (DBS). What Are Your Your EQA responsibilities include: Responsibilities? • Collecting valid specimens • Labeling and store appropriately until transported for re- testing • Ensuring records are properly maintained • Avoiding transcription errors A test result is only as good as the specimen collected. -
