WebMar 28, 2024 · The conversion of naphthalene can vary with the gas residence time as naphthalene conversion reactions can be treated as a first-order reaction. The residence time, or more precisely the space-time, can be experimentally manipulated by either changing the height of the char bed or the velocity of the feed gas.
Webreaction + U fuse = 0 + w Electricity The sample and the fuse both undergo combustion. The electricity from the surroundings (work) heats the wire to a high temperature, and heats the system slightly before it and the sample explode in the nearly 40 atm of O 2 gas. U reaction = w Electricity – [ U hardware + U water + U fuse] H reaction = U WebMay 19, 2015 · Therefore the transition state leading to the 1-isomer will be lower in energy and naphthalene-1-sulfonic acid will be formed fastest - it is the kinetically favored product. However, naphthalene-2-sulfonic acid is a few kcal/mol more stable than its 1-isomer. This is due to an adverse 1,8 steric interaction present in the 1-isomer. ( image source)
WebJan 23, 2024 · The reaction with naphthalen-2-ol. Naphthalen-2-ol is also known as 2-naphthol or beta-naphthol. It contains an -OH group attached to a naphthalene molecule rather than to a simple benzene ring. Naphthalene has two benzene rings fused together. The reaction is done under exactly the same conditions as with phenol.
