A perfluoro-aldehyde is mixed with the perfluorocarbon, and the perfluoro-aldehyde re-orients so that the aldehyde head groups are at the interface.
Optionally, an aldehyde such as butyraldehyde may be present to take part in the condensation.
The invention relates to the utilization of radiohardenable resins based on ketone and urea aldehyde resins.
Artemisinic aldehyde double bond reductase enzymatically reduces artemisinic aldehyde to dihydroartemisinic aldehyde.
Polymerisable materials produced by the reaction of a pyrrole and an unsaturated or polymerisable aldehyde, preferably a beta-unsaturated aldehyde.
The material to be extruded is a thermosetting material that includes at least one member selected from the group of polyamine-aldehyde-containing materials and polyphenol-aldehyde-containing materials.
The invention relates to the utilization of radiohardenable resins based on carbonyl hydrogenated ketone aldehyde and core hydrogenated phenol aldehyde resins.
Coatable urea-aldehyde binder precursor compositions including a urea-aldehyde resin and a cocatalyst yield more consistent quality coated abrasives.
A composition is disclosed, which comprises a hydroxyaromatic-aldehyde resole resin comprising an aldehyde and a hydroxyaromatic compound, modified with a urea-aldehyde condensate.
Therefore, very high catalytic activity and high selectivity in normal-aldehyde or iso-aldehyde according to the type of a substiuent are ensured.
Isolated nucleic acid molecules cloned from Artemisia annua encode artemisinic aldehyde double bond reductase and artemisinic/dihydroartemisinic aldehyde dehydrogenase.
The fatty acid may be a fatty acid or a fatty aldehyde, such as laurinaldehyde, having an acyl chain length of C8-C16.
An optically active amide aldehyde is obtained in the asymmetric reaction by reacting an amide diene and an unsaturated aldehyde compound in the presence of this optically active bisphosphate compound.
The invention relates to a modified hydrocarbylphenol-aldehyde resin prepared by reacting a hydrocarbylphenol-aldehyde resin with a primary or secondary amine and further with an epoxide.
