resin by addition reaction; and R1 is a methyl or ethyl group), with water, the product (b) containing organosilicon compound polycondensates formed in the epoxy resin (a) and having a degree of polycondensation of 2 or higher, and which has a low viscosity at a room temperature (25掳 ...
摘要: The invention relates to highly active spherical metal support catalysts with a metal content of 10 to 70% by mass, and a process for their production with the use of a mixture of polysaccharides and at least one metal compound which is dropped into a metal salt solution....
A photosensitive mixture that contains a photosensitive compound, for example, a photoinitiator or a diazo compound, and a reaction product of a polymer containing active hydrogen with an olefinically unsaturated compound represented by the formula ##STR1## wherein X and Y are the same or differe...
the mixture is pumped in continuously and products are removed continuously. Columns used for this method have many different exit points for different products since they are all being removed simultaneously. Each exit point is placed at a different height on the column, according to where the va...
and then 0.2 ml of 2N methanolic potassium hydroxide solution was added and shaken vigorously for 30 s. The mixture was allowed to stratify until the upper layer solution became clear, and the upper layer containing methyl esters was decanted into 2 ml screw vials. The solution was injected in...
An example would be the analysis of an IgG mixture of six therapeutic proteins with a range of glycosylation patterns; glycosylation is a key post translational modification requiring deep characterization and ma...
: Absorption by chilled or cryogenic liquid is a common method and the most popular, wherein the chilled liquid absorbent is fed concurrently to the flow of hydrocarbon vapours through a packed column, thereby dissolving hydrocarbons in the absorbent and removing it from the air/vapour mixture....
However, there was no obvious correlation between PhnsLTP3 dissociation constants with individual VOCs and a reduction in the emission of the corresponding compound upon PhnsLTP3 downregulation (Supplementary Fig. 22). This could be explained by the fact that petunia flowers produce a mixture of ...
