    What are trans fatty acids‚ and where do they come from? We’re used to hearing about saturated and unsaturated fatty acids. Saturated fatty acids - which come from animal fats (meat‚ lard‚ dairy products) as well as tropical oils such as coconut and palm oils - raise the levels of LDL cholesterol. Unsaturated fats - which come from vegetable oils - in general‚ do not increase cholesterol levels‚ and may reduce them. Because saturated fatty acids were found to be bad for you a couple decades ago

    Recrystallization and Melting Point of Benzoic Acid Organic Chemistry 1 10/4/12 Abstract Recrystallization was done to remove impurities from the sample. The percent recovery of benzoic acid during recrystallization is 23.02%. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure sample had a lower and wider melting point range of 120.1-122.2 (C). The pure sample melting point range was 121.3-122.5 (C). These ranges helped determine

    Title Freezing and Melting Point Objectives 1. To gain proficiency in constructing a graph and plotting data points. 2. To determine the freezing points of a compound from the graph of decreasing temperature versus time. 3. To determine the melting points of a known and unknown compound. Introduction Physical changes are the changes in the physical properties of a substance (Moore‚ Stanitski & Jurs‚ 2009). Freezing point is the fixed temperature at which a pure liquid converted into crystalline

    Lab #1: Melting Points of Organic Compounds Report Form May 15‚ 2014 1. A “Melting Point Range” refers to the range of temperature at which a solid melts into its liquid state. 2. Pure compounds have narrow or ‘sharp’ melting point ranges‚ 1°C or less if the compound is very pure. A less pure compound exhibits a broader melting point range‚ between 3°C to 10°C as well as a depressed or lower range. 3. Crushing the sample allows for greater surface area-to-volume ratio of the powder‚ this

    ------------------------------------------------- MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize an unknown solid in a quick‚ easy and cheap way. The temperature at which a compound turns from a solid state to a liquid state is known to be the melting point. On

    benzoic acid mixture was measured to be 2.075 grams. Following being dried for a week the mass of benzocaine was recorded to be 0.250 grams‚ and benzoic acid was recorded to be 0.600 grams. The melting point range of benzocaine was measured to be 89.5°C-91.5°C‚ while benzoic acid’s melting point range was measured to be 129°C-131.3°C. The percent mass recovered was calculated to be 40.96% for the experiment. Table 1 illustrates the collected information. Starting Mass of Benzocaine/Benzoic Acid: 2.075
