3,4-Dimethyl-1-pentyn-3-ol - Introduction
3,4-dimethyl-1-pentyn-3-ol (CAS number: 565-64-8) is an organic compound often abbreviated as DMWC. The following is an introduction to the nature, use, method and safety information of DMWC:
Nature:
DMWC is a colorless to slightly yellow oily liquid with a special smell. It is soluble in organic solvents such as ethanol, ether and benzene, but poorly soluble in water. The DMWC has a density of 0.831g/cm³ and its boiling point is 165-170 ° C.
Use:
DMWC has a wide range of applications in organic synthesis. It is useful as an intermediate in the synthesis of heterocyclic compounds, Silylation agents, alkanolsilylation agents, and the like. In addition, it can also be used as a surfactant, brazing agent, polymerization catalyst and rubber and plastic additives.
Method:
There are several ways to prepare DMWC. One of the commonly used methods is obtained by the condensation reaction of ethynyl hydroxyacetone with methanol. It can also be synthesized from the reaction between hexadiynol and dimethyl sulfoxide.
Safety Information:
when using or storing DMWC, you need to pay attention to the following safety matters:
1. DMWC is irritating and avoid direct contact with sensitive parts such as skin, eyes and mucous membranes.
2. Use should wash your hands, avoid ingestion or inhalation of its vapor.
3. Should be stored away from the fire and oxidant, to avoid fire or explosion.
4. If taken by mistake or inhaled by mistake, seek medical advice immediately.
5. Avoid the discharge of DMWC into the environment, should take appropriate waste disposal methods.
