Of those, glycerine, ethylene glycol, diethylene glycol, triethylene glycol and propylene glycol are particularly suitable, from the standpoints of depolymerization ability as used in mixtures with said tetra- or higher hydric alcohols e.

As the fatty acid component to be used in the alkyd resin production, fatty acid, oil and fat, and the like may be named. He also know technical aspects about the manufacturing process of proposed plant, and his contribution will be invaluable. In the production of alkyd resin, coloration of formed alkyd resin can be inhibited by adding to the depolymerization product of regenerated PES, in advance of the esterification reaction, a minor amount, e.

Suitable blend ratio of the esterification catalyst is normally 0. Maintaining the same temperature for 4 hours, an ester-interchange reaction of the soybean oil alcoholysis and depolymerization of the regenerated PET were simultaneously carried out.

From Wikipedia, the free encyclopedia. The liquid inks printing process Fountain.

Soft drinks production process flow chart The major raw Alkyd Resin production process Updated. As examples reain useful oil and fat, esters of above fatty acids with glycerine can be named, such as soybean oil, safflower oil, linseed fiketype, tall oil, coconut oil, palm kernel oil, castor oil, dehydrated castor oil, fish oil and tung oil and the like.

In particular, drying or semi-drying oils having iodine values of at least are preferred, inter alia, soybean oil and tall oil are advantageous. Posts Related to epoxy resin manufacturing process process flow sheet. Realbasic Keygen Generator. A SumoBrain Solutions Company.

TECHNICAL FIELD

In the above-described first and second processes, after termination of the esterification reaction, the alkyd resin is normally cooled and may be recovered as it is. Glycol methyl methacrylate The manufacturing process The resin is.

According to the processes of the present invention, transparent alkyd resins, which are nearly free of occurrence of tiletype matters or filtration residues, can be prepared within a short time, using proxess resins which are recovered from waste materials and regenerated. Maintaining said temperature for 2 hours, depolymerization of the regenerated PET was conducted.

It is also preferred to use the polybasic acid component and the fatty acid component at prodction ratios that the carboxyl equivalent numbers in the sum of the polybasic acid component and the fatty acid component per one hydroxyl equivalent in the alcohol mixture falls within a range of 0.

Example 20 was repeated except that 2. The kind produvtion organic solvent is not particularly limited, so long as it can dissolve the alkyd resin.

At that time point the pentaerythritol was dissolved, and into which 5 parts of zinc acetate and 5 parts of litharge were charged, and then parts of regenerated polyethylene terephthalate regenerated PET was charged. Manage your page to keep rwsin users updated View some of our premium pages: This esterification reaction can be conveniently carried out by any method known per se, in the presence of an esterification catalyst such filehype zinc acetate, litharge, dibutyltin oxide and the like.

Manufacturing process of Epoxy resins Most common epoxy resins are produced from a reaction between epichlorohydrin ECH and bisphenol-A BPAthough the latter may be replaced by other raw materials such as aliphatic glycols, phenol and o-cresol novolacs to produce specialty resins.

Examples of tetra- or higher hydric alcohols useful in said alcohol mixture include diglycerine, triglycerine, pentaerythritol, dipentaerythritol and sorbitol. Examples of the allyd and fat, i. Processes for producing within a short time transparent alkyd resins which are substantially free of occurrence of foreign matters or filtration residues are disclosed, which comprise depolymerizing polyester resins whose productkon starting material is terephthalic acid and which have been recovered from waste materials and regenerated, with use of a polyhydric alcohol component having tetra- or higher hydric alcohol, and thereafter adding thereto a polybasic acid component and if necessary a fatty acid component to effect an esterification reaction.

Next Patent Foamed and expanded Furthermore, the alkyd resins obtained by the processes of the invention are transparent and free of turbidity, although they contain terephthalic acid component, and are soluble in weak solvent such as mineral spirits. It is a useful material for the production of hydrolytically stable polyurethanes and dispersions.

On the other hand, recently disposal of waste is becoming a serious issue and utilization of disused PET bottles by recycling is under study.

A process according to claim 1, in which the depolymerization catalyst is used in an amount ranging from 0. Example 26 Example 20 was repeated except aliyd 2. We can predict rarity of cards, the best counters to use vs a given deck and we can even give a preliminary audit for decks that you build. Of alkyd resins using crude Azadirachta indica and aalkyd seed Alkyd.

Also advance blending of liquid oil and fat in said mixture enables stable progress of the esterification reaction between polyhydric alcohol and fatty acid. Click for automatic bibliography generation.

A process according to claim 1 or 2, in which a minor amount of a phosphorus compound is added to the depolymerization product. Heretofore, use of terephthalic acid as the dibasic acid component, which is one of the starting materials of alkyd resins, was more costly than using phthalic acid or phthalic anhydride and the resulting resin was apt to become turbid or develop occurrence of foreign matters.

A new tool, ‘Dynamic Also examples of tri- or lower polyhydric alcohols include: In recent years, the introduction of alkyd latex resin technology has allowed coatings manufacturers to combine the performance advantages of alkyd-based paint chemistries with the convenience of solvent-free, waterborne coatings.

It is also convenient for waterproof property and physical properties of coated film when made dry coated film, to make the equivalent number of carboxyl group s in the polybasic acid component per equivalent of hydroxyl group in said alcohol component 0.
