This invention discloses a method for the directional preparation of 2-methyl-1-butanol from methanol and n-butanol. The aim is to provide a method for the directional preparation of 2-methyl-1-butanol from methanol and n-butanol using methanol and n-butanol as raw materials, directly constructing the molecular framework of the target product, reducing complex separation steps, achieving high product selectivity, and suitable for industrial-scale production. The technical solution is as follows: S1. Add a metal-doped carbon-coated nickel-based catalyst, methanol, n-butanol, water, and an alkaline auxiliary agent to a reaction vessel and mix them evenly to obtain a reaction mixture system; S2. React the reaction mixture system obtained in step S1 at 160-200℃ for 6-24 hours under closed conditions. After the reaction, separate the liquid phase product to obtain a product containing 2-methyl-1-butanol; wherein, the mass ratio of methanol, n-butanol, water, alkaline auxiliary agent, and gallium-doped carbon-coated nickel catalyst is 4:1:5:1.3:0.15-4.5:0.5:5:1.3:0.15; This invention belongs to the field of alcohol catalytic conversion technology.

The invention provides a pet cleaning agent with dual functions of deodorization and softening and a preparation method of the pet cleaning agent, and relates to the technical field of pet supplies. According to the formula prepared by the invention, based on the principles of sterilization inhibition and neutralization degradation, a bactericide, a deodorant and a hair conditioner (a silicone oil conditioner and a cationic conditioner) are compounded to prepare the pet cleaning agent with dual functions of deodorization and softening. The pet hair conditioner can effectively improve the smoothness, bacteriostasis and deodorization performance and durability of pet hair, and can remove odor generated by ammonia gas, methyl mercaptan, isoamylamine, 3-hydroxyisovaleric acid, trimethylamine, 3-mercapto-3-methyl-1-butanol and 3-methylindole on the body surface of a pet.
