This invention belongs to the field of polyether polyol synthesis technology, specifically relating to bio-based high-strength polyether ester polyols and their preparation methods. The bio-based high-strength polyether ester polyol is obtained from the following raw materials: small molecule polyol, catalyst, bio-based epoxide, and bio-based phenyl ester compound; the bio-based epoxide is one or more of limonene epoxide, α-pinene oxide, and caryophyllene oxide; the bio-based phenyl ester compound is one or two of benzyl benzoate and benzyl cinnamate. The raw materials used in this invention can be obtained through natural plant extraction, achieving full bio-based polyether ester polyol production, thus fundamentally reducing dependence on fossil resources. By introducing a large number of cyclic and benzene ring structures into the polyol molecule, the resulting product is applied in the field of rigid polyurethane foam, increasing the content of rigid groups in the molecular chain structure, and significantly improving the strength of rigid polyurethane foam compared to traditional polyether polyols.

This invention discloses the application of benzyl benzoate in the preparation of repellents for red imported fire ants. Experiments verified that after treatment with benzyl benzoate at a concentration of 1 μL / mL or higher for 0.5 h, the feeding and repellency rate of red imported fire ant workers reached 92.74%. After 12 h of treatment, benzyl benzoate at a concentration of 10 μL / mL or higher still maintained a good repellent effect, indicating that benzyl benzoate has a long-lasting repellent activity against red imported fire ants. After treatment with benzyl benzoate at a concentration of 50 μL / mL or higher for 24 h, the burrowing behavior of red imported fire ant workers was significantly reduced. Benzyl benzoate at a concentration of 10 μL / mL or higher showed good repellent effects against red imported fire ants and can be used in future red imported fire ant protective agents; benzyl benzoate at a concentration of 50 μL / mL or higher can be used in red imported fire ant soil repellents.

This invention relates to the field of progesterone preparation technology, specifically to a progesterone lipid liquid crystal suitable for injection, its preparation method, and the pharmaceutical uses of the product. The progesterone lipid liquid crystal injection provided by this invention is a lipid liquid crystal system formed by mixing an oil phase and an aqueous phase. The oil phase includes progesterone, benzyl benzoate, phospholipids, vitamin E, and oleic acid, while the aqueous phase includes water for injection. This invention optimizes the mass ratio of phospholipids to oleic acid in the oil phase to 10:1, and the mass ratio of progesterone, benzyl benzoate, and vitamin E to 2:6:(5-3), resulting in a stable lipid liquid crystal system that improves injection compliance, reduces fat deposition, and achieves sustained drug efficacy for more than 12 hours.

Provided is a superior, novel heterocyclic compound with improved solubility in oil such as sesame oil and benzyl benzoate, which has a broader treatment spectrum, causes less side effects, and is superior in tolerability and safety, and use thereof. A heterocyclic compound represented by the formula (I) wherein each symbol is as defined in the specification, or a salt thereof.

The invention discloses a preparation method of an antibacterial anti-mite blanket, and belongs to the technical field of blanket preparation. The preparation method of the antibacterial and anti-mite blanket is used for solving the technical problem that in the prior art, the antibacterial and anti-mite performance of the blanket needs to be further improved, and comprises the following steps that non-woven fabric is soaked in antibacterial finishing liquid according to the soaking ratio of 1: (30-32), and pretreatment base cloth is obtained after aftertreatment. Benzyl benzoate is used as an anti-mite active component, anti-mite capsules are prepared through crosslinking of sodium alginate, polyvinyl alcohol and delta-glucolactone, the anti-mite capsules are doped into a polyacrylonitrile and dimethylformamide system, modified fibers are prepared through electrostatic spinning, then chitosan and polyhexamethylene biguanide hydrochloride are used as main materials to construct an anti-bacterial finishing liquid, and the anti-mite finishing liquid is prepared through electrostatic spinning. And finally, the antibacterial and anti-mite blanket is obtained through polyurethane hot-pressing compounding, so that not only is the antibacterial and anti-mite performance of the blanket improved, but also the mechanical property of the blanket is improved.
