Reference of 2081-44-9, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 2081-44-9, Name is Tetrahydro-2H-pyran-4-ol, molecular formula is C5H10O2. In a Patent，once mentioned of 2081-44-9
Herbicidal 1-aryl-delta2-1,2,4-triazolin-5-ones
Aryltriazolinones of the formula STR1 in which W is oxygen or sulfur; X1 and X2 are independently selected from halogen, haloalkyl, and alkyl; R is a three- to eight-membered ring heterocyclic group of one or two, same or different, ring heteroatoms selected from oxygen, sulfur, and nitrogen, or an alkyl radical substituted with said heterocyclic group; R1 is alkyl, haloalkyl, cyanoalkyl, alkenyl, alkynyl, or a group of the formula -alkyl-Y–R3 ; R2 is halogen, alkyl, cyanoalkyl, haloalkyl, arylalkyl, or a group of the formula -alkyl-Y–R3 ; R3 is alkyl, alkenyl, or alkynyl; and Y is oxygen or S(O)r in which r is 0 to 2 are disclosed and exemplified.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2081-44-9 is helpful to your research., Reference of 2081-44-9
