It has been shown that a polyetheralkanolamine with 41 moles EO gave the best performance among its homologues and hence we will compare its efficiency with conventional dispersants including a styrene acrylate copolymer, an
acetylenic diol surfactant, and a MSMA.
Swedish colleagues are working on producing
acetylenic fatty acids, which could be used in the production of nylon, specialty chemicals and lubricants.
Review of literature reveals estimation and isolation of various constituents such as flavonoids,
acetylenic thiophenes, teraxasterol and teraxasterol acetates and a considerable number of pentacyclic triterpenoids and their esters (Singh and Pandey, 1990).
Studies have shown that
acetylenic diol based surfactants, such as the Surfynol [R] 400 series surfactants, have less interaction with other formulation components compared to conventional surfactants like alkylphenol ethoxylate, alcohol ethoxylate and some ionic surfactants, so they can be used more effectively at lower dosages without loss of performance.
The syntheses of high-yield carbon-rich materials as
acetylenic precursors, in general, have received much attention [7].
Here we see comprehensive coverage of the cotrimerizations of
acetylenic compounds and glycosylation on polymer supports along with a very helpful list of cumulative chapter titles by volume.

Superbases are well-known reagents in the synthesis of
acetylenic compounds and in different following transformations with them [1-3].
As can be seen from the name of the compound, it has an
acetylenic bond at carbon-12.
The use of
acetylenic monomers bearing fluorine substituents is under study, and it has been found that the resulting polymers do have greatly improved solubility and stability.
