An alkyd is a polyester modified by the addition of fatty acids and other components. Furthermore, the alkyd resins filteype 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. That being said, we have a lot of different places to go and you may need some assistance on prpduction to use the site.

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. Where they are used as resins for room temperature-curing type paints, the drying property can be still improved by concurrent use of metal compound dryers such as cobalt naphthenate, zirconium naphthenate, lead naphthenate and the like.

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. He has been into this industry for more than lastyears. At this time point the pentaerythritol was dissolved, and into which 1.
The regenerated PES is normally used in the form of chips or pulverized product. A process according to claim 2, pproduction which the oil and fat is semi-drying oil or drying oil, and the fatty acid is semi-drying oil fatty acid or drying oil fatty acid. rresin
In the first process of the invention, the depolymerization method of regenerated PES by dissolving it in an alcohol mixture rsin subject to no critical limitation, so long as the regenerated PES can be dissolved in the alcohol mixture and the depolymerization can be effected.
This esterification reaction can be conveniently carried out by any method known per se, filrtype the presence of an esterification catalyst such as zinc acetate, litharge, dibutyltin oxide and the like. According to the processes of the present invention, transparent alkyd resins, which are nearly free of occurrence of foreign matters or filtration residues, can be prepared within a short time, using polyester resins which are recovered from waste materials and regenerated.

This invention relates to processes for producing alkyd resins using polyester resins which have been recovered from waste materials such as disused PET bottles and regenerated. The use rate of such esterification catalyst is normally conveniently within a range of 0. The object of the present invention is to provide processes for producing transparent alkyd resins which are substantially free of foreign matters and filtration residue within a short time, using the polyester resins which have been recovered from waste materials and regenerated.
In particular, drying or semi-drying oils having iodine values of at least are preferred, inter alia, soybean oil and tall oil are advantageous. In particular, recycled polyethylene terephthalate is suitable.
Example 26 Example 20 was repeated except that 2. As the fatty acid component to be used in the alkyd resin production, fatty acid, oil and fat, and the like may be named. On the other hand, recently disposal of waste is becoming a serious issue and utilization of disused PET bottles by recycling is under study.
Process for producing alkyd resin – Kansai Paint Co., Ltd.
January December Home Equipment flow chart of alkyd resin production. Suitable blend ratio of the esterification catalyst is normally 0. Powered by Create your own unique website with customizable templates. Examples of tetra- or higher hydric alcohols useful in said alcohol mixture include diglycerine, triglycerine, pentaerythritol, dipentaerythritol and sorbitol.
It is also preferred to use the polybasic acid component and the fatty acid component producttion such 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. What is claimed is: As examples of useful oil and fat, esters of above fatty acids with glycerine can alkys named, such as soybean oil, safflower oil, linseed oil, fi,etype oil, coconut oil, palm kernel oil, castor oil, dehydrated castor oil, fish oil and tung oil and the like.
Example 20 was repeated except that 2.
Reclaimed poly ethylene terephthalate coating. A process according to claim 1 procss 2, in which the depolymerization catalyst is selected from the group consisting of monobutyltin hydroxide, dibutyltin oxide, monobutyltinethyl hexanoate, dibutyltin dilaurate, stannous oxide, tin acetate, zinc acetate, prodduction acetate, cobalt acetate, calcium acetate, lead acetate, antimony trioxide, tetrabutyl titanate and tetraisopropyl titanate.
Of alkyd resins using crude Azadirachta indica and soybean seed Alkyd. Search Expert Search Quick Search. However, this method is subject to a number of problems such that it requires advance synthesis of the alkyd resin oligomer, requires many hours for the depolymerization and filtration of ultimately obtained alkyd resin causes occurrence of large filerype of filtration residue, because the amount of the alcohol component in the occasion of depolymerization is too low to sufficiently depolymerize the recovered polyester resin.
Babylon 2 0 2 Mac Serial Terminal. Maintaining said temperature for 2 hours, depolymerization of the regenerated PET was conducted. Melamine Formaldehyde Resin Powder of ….
Related This definition includes polyester resins of which alkyds are a particular type. As examples of the phosphorus compound, phosphoric acid, phosphorous acid and hypophosphorous acid; and alkyl esters or phenyl reein of these acids e. A process according to claim 1 or 2, in which the tri- or lower polyhydric alcohol is rpoduction from the group consisting of trimethylolpropane, trimethylolethane, glycerine, ethylene glycol, diethylene glycol, triethylene glycol, resij glycol, 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, neopentyl glycol, 1,6-hexanediol and 1.
As fatty acid, for example, soybean oil fatty acid, safflower oil fatty acid, linseed oil fatty acid, productin oil fatty acid, coconut oil fatty acid, palm kernel oil fatty acid, castor oil fatty acid, dehydrated castor oil fatty acid, fish oil fatty acid and tung oil fatty acid may be named.
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.
Hereinafter the first and second processes of the invention are explained in further details. Depolymerization conditions of regenerated PES are not subject to critical limitations, so long as they allow the depolymerization using a depolymerization catalyst.
Recently overcoatability is attached greater importance and alkyd resins soluble in weak solvent are highly evaluated.
Those alkyd resins obtained by the first and second processes of the present invention are excellent in solubility in organic solvent, are soluble in even produciton weak solvent as mineral spirits although they contain terephthalic acid component, and are useful as resin binder in paint compositions. What is ‘Clash Royale Deck Builder’? The kind of organic solvent is not particularly limited, so long as it can dissolve the alkyd resin.
Then conducting dehydration condensation reaction at said temperature, an alkyd resin was obtained.
