... other. For example, acids should not be stored near cyanides, sulfides and other chemicals that produce toxic gases when combined. Acids should also not be stored near bases or active metals. Reactions between acids and bases produce heat. Acids and active metals react to produce gases and heat. Aci ...

Unit 8 – Organic Chemistry
... Intro to Organic Chem • Up to this point, no organic compound had been synthesized from inorganic materials and, as a result, many scientists believed that organic compounds were formed only under the influence of a vital force. • It was Friedrich Wöhler (1800–1882) who, in 1828, made a remarkable ...

Rapid Microwave Synthesis, Characterization and Reactivity
... The thermal stability of the nitride hydride was investigated by TG-DTA under flowing argon. TG-DTA of sample 8 showed no evidence of mass change and hence decomposition or dehydrogenation when the sample was heated to 773 K (Figure 5a). Moreover, it was also evident from mass spectra collected simu ...

Esterification
... • Research has identified 11 different esters in grape juice, but wine can have up to 83; this affects the wine’s flavour and complexity in proportion to their presence. Esters are formed when an acid reacts with alcohol, eliminating a water molecule in the process. Ethyl esters have a strong influe ...

Properties of haloalkanes
... Primary haloalkanes do not react with water, but react to form alcohols with aqueous sodium hydroxide. Formation of amines Another nucleophilic substitution reaction occurs between haloalkanes and alcoholic ammonia: R—X + NH3(alc) → R—NH2 + HX amine It must be alcoholic ammonia: if water is present ...

... and they usually require high temperatures and/or long react ion times, and side reactions, such as isomerization, epimerization and rearrangements may be induced by the alkaline conditions. Furthermore, high temperatures are not only detrimental to certain functional groups, but also to the control ...
