Method for producing low-melting-point renewable polyester for sheath-core polyester through glycol degradation

The invention relates to a method for producing low-melting-point renewable polyester for sheath-core polyester. The low-melting-point renewable polyester is prepared from the following raw materials through degradation and polycondensation: (a) renewable raw materials; (b) glycol; (c) one or more of zinc acetate, potassium acetate, manganese acetate, magnesium acetate, lead acetate, cobalt chloride, tetrabutyl titanate, tetraisopropyl titanate and dibutyltin dilaurate; (d) one or more of m-phthalic acid, adipic acid and sebacic acid; (e) one or more of neopentyl glycol, hexanediol, butanediol and polyethylene glycol; (f) catalysts, namely antimony trioxide and cobalt acetate; and (g) a stabilizer, namely trimethyl phosphate. The low-melting-point renewable polyester produced by the method can be applied to the preparation of sheath-core polyester staple fibers, so that the added value of polyester wastes in preparation of renewable polyester staple fibers is increased, and the prepared sheath-core renewable polyester staple fibers have the characteristics of stable quality and excellent quality. The method can be applied to the production of industries, such as non-woven fabrics, flocking and composite materials.

New cancer-resisting use of fritillaria cirrhosa total alkaloids and compounds contained in fritillaria cirrhosa total alkaloids

The invention provides use of fritillaria cirrhosa total alkaloids in preparing drugs for inhibiting multiplication of eukaryote tumor cells. The invention also provides new cancer-resisting use of compounds in fritillaria cirrhosa. The fritillaria cirrhosa total alkaloids can inhibit the multiplication of the eukaryote tumor cells, has an effect on curing tumors and can be used for curing multiple tumors. With the same dose, the drug effect of the fritillaria cirrhosa total alkaloids is obviously better than the compound peimine and peiminine. The fritillaria cirrhosa total alkaloids have stable quality, are safe to use and are easy to control, the preparation method is simple, and the mass production and clinical use can be conveniently realized. Monomeric compounds such as chuanbeinone, kashmirine, imperialine-beta-N-oxside, isoverticine, isoverticine-beta-N-oxide and peimisine contained in the fritillaria cirrhosa total alkaloids also can inhibit the multiplication of the eukaryote tumor cells and have an effect on curing the tumor; and with the same dose, the drug effect of the monomeric compounds in the fritillaria cirrhosa total alkaloids is obviously better than that of peimine and peiminine, and a new choice for clinically curing the tumor is provided.

Method for preparing chitosan into water-soluble chitooligo saccharide

ActiveCN101643516AProduce noneDischarge noSlagFiltration
The invention relates to a method for preparing chitosan into water-soluble chitooligosaccharide, which comprises the following steps: using chitosan as a raw material, processing the chitosan by rinsing and drying technology, and immersing the chitosan in a material liquid prepared by purified water and edible hydrogen peroxide; carrying out the processing of microwave radiating degradation to form the mixed liquid of low-molecular chitooligo saccharide which can be dissolved in the material liquid and partial undegraded chitosan, and obtaining residual slag of chitosan and a chitooligo saccharide solution by filtration; and sending the chitooligo saccharide solution into absolute ethyl alcohol, and after alcohol precipitation, carrying out sucking filtration and drying to obtain a finished product of water-soluble chitooligo saccharide. The processing technology of microwave radiating degradation is used, and energy is mased by a physical method to degrade high-molecular chitosan into low-molecular water-soluble chitooligo saccharide with a stable structure, thus no other side product of reaction or pollutant is generated in the degrading process. Compared with the preparing method of the prior art, the invention has the advantages of advanced technology, simple procedures, low investment of production facilities, high product purity, stable quality and the like, and developsa wide market application prospect for the chitosan prepared by taking chitin as a raw material.

A kind of hydrochloric acid vegetable production method

The invention discloses a production method of salted and pickled vegetables, comprising the following steps of: cleaning and airing green vegetables, and then adding salt to pickle for 90-120 days; cleaning and slitting the well pickled green vegetable raw materials; carrying out desalting and dewatering treatment, and then adding the following condiments in parts by weight in terms of 1000 parts of the green vegetables: 150-250 parts of sweet wine, 60-80 parts of crystal sugar, 10-30 parts of hot peppers and 10-20 parts of pickled garlic; and blending, and then placing into a jar again to ferment for 7-10 days so as to obtain the salted and pickled vegetables. The production method of the salted and pickled vegetables is summarized by the applicant by combining with years of production experience of the Dushan salted and pickled vegetable and strictly controlling various parameters and ingredients of a production process. According to the production method of the salted and pickled vegetables, the pickling time of the green vegetables is controlled within 3-4 months according to seasons and temperature, the desalting and dewatering treatment is carried out on the pickled green vegetables to regulate the salt and water contents of the green vegetables, and various condiments and using amounts thereof are carefully chosen to carry out secondary fermentation on the pickled vegetables, and therefore the pure taste and the stable quality of a salted and pickled vegetable product can be achieved.
