CONSTITUTION:The objective stable hydrated block isocyanate is produced by synthesizing a hexamethylene diisocyanate-type polyisocyanate compound containing isocyanurate ring structure in the molecule from hexamethylene diisocyanate, dissolving the polyisocyanate compound in ethyl acetate, etc., adding butanone ...
Which of the following is an organic molecule? A. Water B. Hydrogen gas (H2) C. A hydrocarbon D. Ammonia (NH3) Which is a polar aprotic solvent? a. 2-methyl-2-propanol b.CH_3CH_2CH_2OCH_2CH_2CH_3 c.NH_3(I) d.2-methylhexane e.CCI_4...
These compounds usually have a plane of symmetry within the molecule.Answer and Explanation: The first compound is not a meso compound. This compound contains 2 chiral carbon atoms and has no plane of symmetry. Thus, overall, the compound is......

CONSTITUTION:The objective stable hydrated block isocyanate is produced by synthesizing a hexamethylene diisocyanate-type polyisocyanate compound containing isocyanurate ring structure in the molecule from hexamethylene diisocyanate, dissolving the polyisocyanate compound in ethyl acetate, etc., adding butanone ...
The polyhydroxy polyacrylates preferably have at least two alcoholic hydroxyl groups per molecule as a statistical average, although a small portion of monohydroxyl compounds may be present. The polyhydroxy polyacrylates may be prepared by known methods such as those described in European Patent Offic...
The number-average molecular weight, Mn of the binder or hydroxylated polymer of the present invention ranges between 2000 and 15,000 g/mol, its degree of branching (that is to say the average number of free OH functions per molecule) is between 2 and 4. The molecular weight is determined...
(e.g. hydroxymethyl), morpholino, hydroxy or --NHCOR6 where R6 is C1-3 alkyl (e.g. methyl), or Ar is a phenyl group substituted by hydroxyl groups at the 3- and 5-positions or Ar represents a pyridyl group attached to the rest of the molecule at the 2-, 3- or 4- position, ...
In the case of the component B) it is a question of monovalent polyalkylene oxide polyether alcohols comprising, on statistical average, 5 to 35, preferably 7 to 30, ethylene-oxide units per molecule, such as are available, in a manner known as such, by alkoxylation of suitable starter mol...
