Description
染料は、特にポリエステル材料に可溶な、天然又は合成の物質であり、ポリエステル材料を着色するために、その材料の中に導入されて使用される。一般的に使用される染料は、それぞれ異なる性質を有し、しばしば、O型及びN型のヘテロ原子と、共役不飽和結合とを有しており、例えば、キノン、メチン、若しくはアゾ官能基、又はピラゾロン及びキノフタロン等の分子が挙げられる。顔料は、特にポリエステル材料に不溶な微細に分割された物質であり、材料を着色及び/又は不透明化するために、その材料の中に導入されて使用される。ポリエステル、特にPETを着色及び/又は不透明化するために使用される主な顔料は、TiO2、CoAl2O4、又はFe2O3等の金属酸化物、ケイ酸塩、ポリスルフィド、並びに、カーボンブラックである。顔料は、一般的に0.1~10μm、圧倒的に0.4~0.8μmのサイズを有する粒子である。ろ過によりこれらの顔料を完全に除去することは、不透明PETの再生処理を想定するためには必要であるが、顔料は極端に高い閉塞性を有するため、技術的に困難である。
Dyes are substances, natural or synthetic, which are particularly soluble in polyester materials and are used by being introduced into the polyester materials to color them. Commonly used dyes have different properties and often have O-type and N-type heteroatoms and conjugated unsaturated bonds, such as quinone, methine, or azo functional groups, Or molecules such as pyrazolones and quinophthalones. Pigments are finely divided substances that are insoluble in particular in polyester materials and are used by being introduced into the material to color and/or opacify the material. The main pigments used to color and/or opacify polyesters, especially PET, are metal oxides such as TiO2 , CoAl2O4 , or Fe2O3 , silicates, polysulfides, and carbon Black. Pigments are particles generally having a size of 0.1 to 10 μm, predominantly 0.4 to 0.8 μm. Complete removal of these pigments by filtration, which is necessary to envision recycling of opaque PET, is technically challenging due to the extremely high occlusive properties of the pigments.
有利には、重合添加剤及び触媒が、重縮合段階c)に導入され得る。非制限的な例として、添加剤は、例えば、アミン(n-ブチルアミン、ジイソプロピルアミン、若しくはトリエチルアミン)、水酸化ナトリウム、有機水酸化物、炭酸リチウム等のエーテル化副反応阻害剤と、亜リン酸塩又はリン酸塩等の安定剤と、アセトアルデヒド等の分解生成物の量を低減させるためのポリアミドタイプの化合物とを含み得る。一般的に使用される重合触媒は、例えば、アンチモン、チタン、ゲルマニウム、アルミニウム、酢酸亜鉛、カルシウム、マンガンをベースとする触媒等である。
Advantageously, polymerization additives and catalysts can be introduced in the polycondensation stage c). Non-limiting examples of additives include etherification side reaction inhibitors such as amines (n-butylamine, diisopropylamine, or triethylamine), sodium hydroxide, organic hydroxides, lithium carbonate, and phosphorous acid. Stabilizers such as salts or phosphates and polyamide type compounds to reduce the amount of decomposition products such as acetaldehyde may be included. Commonly used polymerization catalysts are, for example, antimony, titanium, germanium, aluminum, zinc acetate, calcium, manganese based catalysts and the like.
有利には、段階d)の前記回収セクションには、段階c)で得られたジオール流出物の全部又は一部が、好ましくは液体の形態で、少なくとも供給される。加えて、段階a)のジエステルモノマー供給原料が、再生処理されるべきポリエステル供給原料の解重合のための方法の終わりに得られる精製されたジエステル流出物のフラクションを少なくとも含む、本発明の有利な実施形態である場合、段階d)の前記回収セクションには、再生処理されるべきポリエステル供給原料の解重合のための方法の段階ii)の分離セクションに由来するグリコール流出物の全部又は一部が供給され得る。場合により、本発明による方法の段階d)の前記回収セクションにはまた、外部から補われるジオールが供給され得る。有利には、回収セクションは、少なくともジオールモノマーを含む異なる流れをろ過する操作を1回以上含み得る。
Advantageously, said recovery section of step d) is at least fed with all or part of the diol effluent obtained in step c), preferably in liquid form. In addition, the advantageous process of the present invention, wherein the diester monomer feedstock of step a) comprises at least a fraction of the purified diester effluent obtained at the end of the process for depolymerization of the polyester feedstock to be reclaimed. In an embodiment, said recovery section of step d) contains all or part of the glycol effluent from the separation section of step ii) of the process for depolymerization of a polyester feedstock to be reclaimed . can be supplied. Optionally, said recovery section of step d) of the process according to the invention can also be supplied with externally supplemented diol. Advantageously, the recovery section may comprise one or more operations of filtering different streams containing at least the diol monomer.
反応流出物中に存在するエチレングリコールを、200℃~124℃の範囲の温度、0.1MPa~0.00025MPaの圧力での、一続きの5つの容器内における蒸発により分離した。この蒸発段階の終わりに、97重量%のMEG、2.5重量%のDEG、0.2重量%の水、0.2重量%のBHET、及び5.17t/時間のBHETを豊富に含む液体流れからなる、10.95t/時間のMEGの流れを回収した。MEGの流れを、25個のプレートを備え、かつ塔頂において、145℃、0.02MPaで操作される、第1の蒸留に送った。これにより、DEG及び重質生成物を分離した。次いで、17個のプレートを備え、かつ塔頂において、100℃、0.1MPaで操作される、第2の蒸留塔に送った。これにより、水を分離して、精製されたMEG流出物を回収した。MEG流出物は、後に、補足された新鮮なMEGとの混合物として、解重合反応器に再循環させることができる。BHETを豊富に含む液体流れは、87.1重量%のBHET、0.2重量%のMEG、0.1重量%のDEG、12.6重量%のオリゴマー、顔料、及び他の重質化合物を含んでいた。 Ethylene glycol present in the reaction effluent was separated by evaporation in a series of five vessels at temperatures ranging from 200° C. to 124° C. and pressures from 0.1 MPa to 0.00025 MPa . At the end of this evaporation stage, a liquid rich in 97 wt.% MEG, 2.5 wt.% DEG, 0.2 wt.% water, 0.2 wt.% BHET and 5.17 t/h BHET A stream of 10.95 t/h of MEG was collected, consisting of streams. The MEG stream was sent to a first distillation equipped with 25 plates and operated at 145° C. and 0.02 MPa at the top of the column. This separated DEG and heavy products. It was then sent to a second distillation column equipped with 17 plates and operated at 100° C. and 0.1 MPa at the top. This separated the water and recovered the purified MEG effluent. The MEG effluent can later be recycled to the depolymerization reactor as a mixture with supplemented fresh MEG. The BHET-rich liquid stream contained 87.1 wt% BHET, 0.2 wt% MEG, 0.1 wt% DEG, 12.6 wt% oligomers, pigments, and other heavy compounds. contained.
