The present invention relates to a composition, which is useful for producing coatings for metal sheet substrates of metal cans for storing and / or transporting food or beverages or a lid thereof, and which comprises the following components:(a) 30 to 90 wt. % of a polyvinylchloride-(PVC)-polymer,(b) 7 to 25 wt. % of an acrylic resin,(c) 3 to 40 wt. % of a crosslinking agent, which is produced from phenol, para-tert.-butylphenol, xylenol or a mixture thereof, and formaldehyde,(d) 0 to 8 wt. % additive,(e) 0 to 50 wt. % pigment and(f) a solvent-component,where all weight percentages are on the basis of the total dry weight of the coating composition (without solvents) and the composition is substantially free of bisphenol-A-diglycidyl-ether (“BADGE”) and also substantially free of bisphenol-A-resins. The composition provides metal can coatings that have suitable flexibility, scratch resistance, adherence and sterilization resistance when processed in contact with food. The coatings are suitable for three-piece cans as well as deep-drawn metal cans. In particular they are, however, useful for lids that are to be torn open due to their extraordinary flexibility and sterilization resistance.

The present invention relates to a toughening method of poly(3-hydroxy butyrate) and poly(3-dydroxy butyrate-3-hydroxy pentanoate). The raw material includes the first component of poly(3-hydroxy butyrate) or poly(3-dydroxy butyrate-3-hydroxy pentanoate) with 3-hydroxy pentanoate monomer molar content less than 20%; the second copmonent of p-tert-butylphenol, bisphenol A, bisphenol S or 2,4,6-tri(2'-hydroxy-4'-butoxyphenyl)-1,3,5- triazine; and the optional component including plasticizer and stuffing. The weight ratio between the first component and the second component is 70-90 to 10-30 andthe optional component is 0-30 wt% of the first component. By means of solution blending or melting blending, modified material with excellent toughness may be obtained.

The invention discloses a chemical synthesis method, in particular to a preparation method of high-cis vertenex. The vertenex is prepared from two steps of reactions: firstly, using p-tert-butyl phenol and hydrogen as raw materials to synthesize tert-butyl cyclohexanol under the condition of a catalyst; secondly, using tert-butyl cyclohexanol and acetic acid as raw materials to carry out a synthesis reaction under the condition of a catalyst III to obtain high-cis vertenex. The invention has the advantages of mild reaction conditions, safe and convenient operation, high cis body content in the product and thinner and stronger and fine product fragrance. The method can be widely applied to the preparation process of perfume.

The invention relates to a morpholine modified para-tert-butyl phenolic resin and is characterized in that the structural formula of the morpholine modified para-tert-butyl phenolic resin is described in the specification, wherein R is morpholine, n can be 1,2,3,4 or 5, and the average molecule weight of the substance is 800-1000. According to the invention, the resin can improve the tackifying property of a product so that the tackifying property of the product meets the processing technology of automobile tyre and rubber; and the performance of the resin is equivalent to that of para-tert-butyl phenol-acetylene resin produced by BASF in German. The invention also discloses the preparation process of the morpholine modified para-tert-butyl phenolic resin.

A solvent-free method for preparing trackifying para-tertiary butyl phenol phenolic resin comprises the following components and dosage, with the dosage of weight part: 900-1000 parts of para-tertiary butyl phenol, 150-200 parts of 97% formaldehyde, 40-50 parts of 10% hydrochloric acid, 5-10 parts of oxalic acid, and 1.5-3.5 parts of surface-active agent, wherein, 97% formaldehyde and 10% hydrochloric acid are both weight percentage. The method overcomes the shortcoming of the existing method for preparing para-tertiary butyl phenol phenolic resin, which uses solvent; and the method has the advantages of simple synthetic process, low production cost and higher performance than that of the existing product, and avoids sudden gathering in the process of preparation, and the like.

The invention discloses a manufacturing method for preparing methanol diesel fuel from industrial methanol. The method comprises the following steps of: putting ethanolamine and naphthenic acid into the industrial methanol according to a certain proportion and mixing to obtain denatured methanol for later use; selecting alkylphenol ethoxylates, dimethyl carbonate, ethyl oleate and para-tert-butyl phenol according to a proportion, sequentially adding the alkylphenol ethoxylates, the dimethyl carbonate, the ethyl oleate and the para-tert-butyl phenol into a container and stirring for 20 to 30 minutes so as to obtain a methanol diesel fuel modifier for later use; and adding 75 percent diesel fuel mixed liquor into 20 percent denatured methanol, stirring fully and uniformly, adding 5 percent diesel fuel modifier and fully mixing so as to obtain finished methanol diesel fuel. A methanol diesel fuel product has the advantages of no delamination, high stability, no corrosion, no swelling, no emulsification, high explosive force, convenient use, readily available raw materials, low manufacturing cost and easy popularization.

The invention relates to a treatment method for waste salt water generated in the production process of polycarbonate. The treatment method comprises the following steps: the temperature of the wastesalt water generated in the production process of the polycarbonate PC and containing bisphenol A, p-tert-butylphenol and quaternary ammonium salt is regulated to 20-60 DEG C by a heat exchanger, thenthe waste salt water is introduced into an acid-regulating kettle, and the pH value is regulated to 1-4; then trace suspended solids are removed by a coarse filter and a precise filter, and the wastesalt water is conveyed to a high-position groove; the waste salt water flows into macroporous resin adsorbing columns by gravity to be adsorbed, then enters an alkaline-regulating kettle, and the pHvalue is regulated to 10-14; finally, the waste salt water enters active-carbon adsorbing columns to be adsorbed. The treatment method has the beneficial effects that phenolic organic matters in the waste salt water of the PC can be completely removed, and most of quaternary ammonium salt is removed; in the treated salt water, the content of the quaternary ammonium salt is less than 1ppm, the content of TOC (Total Organic Carbon) is less than 10ppm and the content of TN (Total Nitrogen) is less than 3ppm; as a raw material, the treated salt water can be used for a process for preparing causticsoda by a chlor-alkali ion membrane, and can not cause increase of voltage of an electrolytic cell, so that sodium chloride and water in the waste salt water can be recycled, and the recycling of thematerials is realized.

This rubber composition for a tire is obtained by blending a rubber component (A), zinc oxide (B), and a co-condensate (C) that has a softening point of 150 DEG C or less and that contains a p-tert-butylphenol-derived constituent unit represented by formula (1), an o-phenylphenol-derived constituent unit represented by formula (2), and a resorcinol-derived constituent unit represented by formula (3). The nitrogen adsorption specific surface area (N2SA) of the zinc oxide (B) according to the BET method is 6-110 m<2> / g. The blending amount of the zinc oxide (B) is 5-13 parts by mass with respect to 100 parts by mass of the rubber component (A). The blending amount of the co-condensate (C) is 0.1-10 parts by mass with respect to 100 parts by mass of the rubber component (A). The co-condensate (C) can be used as a replacement for p-tert-octylphenol and p-nonylphenol, has a softening point that is lower than the maximum temperature in a rubber processing step, and has excellent dispersibility in rubber.
