2. Using o-chlorobenzaldehyde and alkali metal salts of thioglycolic acid as raw materials Kokai et al. (JP 05194484) used o-chlorobenzaldehyde and alkali metal salts of thioglycolic acid as raw materials to first condense and form the intermediate 2-formylphenylthioacetate. The intermediate undergoes...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
A vapor barrier is installed, then drywall. This situation is really bad, water vapor from the concrete escapes into the stud cavity and condenses on the back of the vapor barrier behind the drywall. Again, water creates a nasty mold situation in the stud bay....
The thermal decomposition of APP produces free acidic hydroxyl groups, which condense through thermal dehydration and produce highly cross-linked structures. Polyphosphoric acid reacts with polymers containing oxygen and nitrogen, catalyzing dehydration and charring formation. However, the effect of APP ...

to make sense. The process of accreting hierarchically from smaller building blocks is termed core accretion, but there has been something of a debate surrounding gas giants like Jupiter. Can they condense straight out of the gas of the solar nebula like a star, or do they need a large ...
to ‘devour’ and critically assimilate not only the values transplanted to the colony but also those which had been denied, particularly the local, native and popular. Andrade’s parody of the Hamletian impasse condenses the identity tension and segmentation, and also the will of producing a ...
