sec

sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH 3 CH 2 CH(NH 2)CH 3. It is a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine, and isobutylamine. sec-Butylamine is chiral and therefore can exist in either of two enantiomeric forms.

The Mechanism of the Formation of a

oxidation to secondary butyl amine and carbon dioxide with hydrazoic acid. The secondary butyl amine was oxidized to methyl ethyl ketone by the dropwise addition of alkaline KMn04 in the cold over a 3- to 5-hour period. Excess permanganate was destroyed by the addition of MnSOc and ketone

Butyl Group

Two isomers of butane exist, n-butane, also called 1–butane (CH 3 CH 2 CH 2 CH 3 ), and iso-butane, also called 2-methylpropane (CH 3 CH (CH 3 )CH 3 ). Removing a hydrogen atom from the first isomer can result in the formation of two different butyl groups, one designated as n-butyl,

Synthesis and selection of hindered new amine absorbents

To achieve this target we synthesized seven secondary and two tertiary amine based CO 2 absorbents with systematic modification of their chemical structures by an appropriate placement of substituent functional groups especially the alkyl functions (e.g. methyl, isopropyl, isobutyl, secondary butyl etc.), relative to the position of the amino group.

A newly introduced neutralising amine for waterborne coatings, secondary-butyl ethanolamine or sBEA, has an amphiphilic structure, through which it can assist dispersants in separating and binding topigment particles. Tests on a blue tinting base show that sBEA provides greater pigment efficiency and better flow properties than classical amines such as DMEA.

Synthesis of Alcohols

The Grignard reaction is the only simple method available that is capable of producing primary, secondary, and tertiary alcohols. To produce a primary alcohol, the Grignard reagent is reacted with formaldehyde. Reacting a Grignard reagent with any other aldehyde will lead to a secondary alcohol.

How can we see from the formula which one is the primary

In a primary alcohol, the carbon atom bearing the OH group is attached to one other carbon atom or alkyl group (R), in a secondary alcohol it is attached to two alkyl groups (R and R') and in a tertiary alcohol to three alkyl groups (R, R', R''). In each case, R, R' and R'' may be the same or different.
