The relationship between reactant concentration and reaction time-first-order reaction, second-order reaction and third-order reaction
Time of Update: 2021-06-18
That is, the time required for each half of the concentration of the reactant to be consumed is a constant, so the reaction is a first-order reaction, t 1/2 = 2min .

The relationship between reactant concentration and reaction time-zero order reaction
Time of Update: 2021-06-18
The integral expression of the zero-order reaction can also be written as[A] 0 -[A] t =k tThat is, the change in reactant concentration is proportional to time .

Phosphorus-containing reactants for UV-cured wood coatings.
Time of Update: 2020-10-28
Researchers have recently developed a phosphorus-containing reactive agent for ultraviolet curing, flame retardant wood coatings.
attempts to develop UV-RA, a phosphorous-based flame retardant for coating applications, have led to the synthesis of reactive compounds that can be used as UV crosslinkers and UV-cured epoxy acrylates low-polypolymers to form coatings.
