814 ACETYLENIC DIOL ACRYLIC ADHESIVE TABLE 13 -- Printing Ink, Key Pyrolysis Products at 600[degrees]C RETENTION TIME COMPOUND 2.

Similarly to 14, the imaginary frequency of transition state 22 corresponds to the elongation of the C-H bond of the acetylenic proton.

Tailoring the Properties of Boron-Dipyrromethene Dyes with Acetylenic Functions at the 2,6,8 and 4-B Substitution Positions.

Preparative Acetylenic Chemistry, Elsevier: Amsterdam, 2nd ed.

Some researchers reported that the genus Echinops are consist of flavonoids, alkaloids, saponins, phytosterols, polyphenols, carotenoids, sesquiterpene lactones/alcohols, lignans, acetylenic and thiophene compounds and essential oils (Tadesse and Abegaz, 1990; Singh and Pandey, 1994; Hymete et al.

1] (200, which is associated with the acetylenic C--H stretch, was observed also.

Acetylenic fatty acids (8-16 carbons) are one of the most promising groups of fatty acids to exert antifungal effects (29), while a-methoxylated fatty acids are less toxic (30).

Antihyperglycemic acetylenic glucosides from Bidens pilosa.

Topics addressed include bioactive macrocyclic peptides and peptide mimics, macrocycles by ring-closure metathesis, supramolecular macrocycle synthesis by H-bonding assembly, cucurbiturils, tetra-urea calixarenes, shape-persistent macrocycles based on acetylenic scaffolding, supramolecular 3D architectures by metal-directed assembly of synthetic macrocycles, new properties and reactions in self-assembly M6L4 coordination cages, anion-binding macrocycles, and rotaxane and catenane synthesis.

Caulerpenyne, a unique acetylenic sesquiterpenoid that is closely related to flexilin, was first isolated from a Mediterranean collection of C.

Once the optimum molecule was achieved, its performance in pigment concentrates with and without a resin was compared to other conventional dispersants such as a styrent acrylate copolymr, an acetylenic diol surfactant, and a styrene maleic anhydride comb polymer modified with a polyether.

Typical inhibitors are materials that have higher affinity for platinum than the siloxane polymer vinyl group and include such materials as peroxides, hydroperoxides, and acetylenic derivatives.

The flower oil contains as minor constituents two acetylenic thiophenes: 5'-methyl-5-(3-buten-1-ynyl)-2,2'-bithienyl (2) (Fig.

To the extent that both components originate from the same source, acetylenic free radicals that generate polyaromatic structures in the flaming stage of combustion, one would expect similar [.
