The branching in 2-ethyl-1-butanol makes it harder to crystallize due to packing disruption, which results in a very low freezing point. Esters of 2-ethyl-1-butanol are similarly effected and it therefore finds application as a feedstock in the production of plasticizers and lubricants, where its presence helps reduce viscosity and lower freezing points.
Crotonic acid ((2E)-but-2-enoic acid) is a short-chain unsaturated carboxylic acid described by the formula CH 3 CH=CHCO 2 H. The name crotonic acid was given because it was erroneously thought to be a saponification product of croton oil . [ 2 ]
Multiple double bonds take the form -diene, -triene, etc., with the size prefix of the chain taking an extra "a": CH 2 =CHCH=CH 2 is buta-1,3-diene. Simple cis and trans isomers may be indicated with a prefixed cis-or trans-: cis-but-2-ene, trans-but-2-ene. However, cis-and trans-are relative descriptors.
Hagemann's ester, ethyl 2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann. The compound is used in organic chemistry as a reagent in the synthesis of many natural products including sterols , trisporic acids , and terpenoids .
Morpholine is an organic chemical compound having the chemical formula O(C H 2 CH 2) 2 NH. This heterocycle features both amine and ether functional groups. Because of the amine, morpholine is a base; its conjugate acid is called morpholinium. For example, treating morpholine with hydrochloric acid generates the salt morpholinium chloride.
1-Butene (IUPAC name: But-1-ene, also known as 1-butylene) is the organic compound with the formula CH 3 CH 2 CH=CH 2. It is a colorless gas. But-1-ene is an alkene easily condensed to give a colorless liquid. It is classified as a linear alpha-olefin (terminal alkene). [2] It is one of the isomers of butene (butylene). It is a precursor to ...
2 – CH=CH –H (3-butenoic). All have the chemical formula C 3 H 5 COOH or C 4 H 6 O 2. These compounds are technically mono-unsaturated fatty acids, although some authors may exclude them for being too short. The three isomers are: crotonic acid (trans-2-butenoic or (2E)-but-2-enoic acid) isocrotonic acid (cis-2-butenoic or (2Z)-but-2-enoic ...
Butene, also known as butylene, is an alkene with the formula C 4 H 8.The word butene may refer to any of the individual compounds. They are colourless gases that are present in crude oil as a minor constituent in quantities that are too small for viable extraction.
