生產間苯二甲酸二乙酯Between the production of diethyl phthalate
由間苯二甲酸制備的間苯二甲酸二乙酯（DEIP）主要用于甲苯二異氰酸生產中做特種溶劑，Prepared from isophthalic acid, diethyl isophthalate (DEIP) is mainly used for the production of toluene diisocyanate to do special solvent,具有溶解性能好，易于分離，可加速光氣反應，減少副反應，產品純度高等特點。Has good solubility, easy separation, can accelerate phosgene, reduce side effects, and high product purity.
由間苯二甲酸二苯酯和3，3’-二氨基聯苯胺（DAB）進行熔融縮聚反應制得的聚苯并咪唑是雜環高分子中個被考慮用作耐高溫結構膠粘劑的產品，Isophthalic acid and 3,3-diamino-diphenyl-benzidine (DAB) were prepared by melt polycondensation reaction is a heterocyclic polybenzimidazole polymer is used as the first to be considered in high-temperature structural adhesive products,其特點是瞬時耐高溫性能優良，廣泛用作鋁合金、不銹鋼等金屬材料、金屬蜂窩結構、聚酰亞胺薄膜以及硅片等材料的膠粘劑。Which is characterized by excellent transient temperature performance, are widely used as aluminum, stainless steel and other metal materials, adhesives, metal honeycomb structure, and a polyimide film of silicon and other materials.
生產陽離子可染樹脂改性單體Production of cationic dyeable resin-modified monomeric
由間苯二甲酸制得的間苯二甲酸二甲酯-5-磺酸鈉（SIPM）是聚酯切片的改性單體，Prepared from isophthalic acid, dimethyl isophthalate 5-sodium (SIPM) is a modified monomer of polyester chips,可使改性后的聚酯纖維染色更鮮艷濃厚，著色性好，同時具有抗起球效果。Modified polyester fiber dyeing make strong after more vivid coloring is good, but also has anti-pilling effect.在聚酯切片中引入SIPM可生產陽離子改性滌綸長絲Introduction SIPM produce cationic modified polyester filament polyester slices，其外觀雖然與普通滌綸長絲沒有太大的區別，Although its appearance and ordinary polyester filament is not much difference,但是由于采用了陽離子改性，不僅大大改善了纖維的吸色性能，However, due to the use of cationically modified, not only greatly improve the color absorption properties of the fibers,而且降低了結晶度，從而使染色分子易于滲透，使得纖維容易染色。But also reduces the degree of crystallinity, so that the dye molecule is easy to penetrate the fibers easily dyed.這種纖維既保證了陽離子易染，同時又可增加纖維的微孔，This fiber is easy both to ensure the cationic dye, but also increase the fiber pores,提高了纖維的上染率、透氣性、吸濕性，從而進一步適應聚酯纖維的仿真絲化。Improve the fiber dyeing rate, permeability, moisture absorption, thereby further adapt silk of polyester fibers.通過仿真絲化可使織物柔軟透氣、舒適、抗靜電、常溫常壓可染。Make by silk fabric of soft, breathable, comfortable, antistatic, temperature and pressure can be dyed.通過陽離子改性多功能仿毛，可使織物具有手感柔軟、抗靜電、抗起毛起球、常溫常壓與毛共染。By cation-modified multifunctional wool, make fabric has a soft, antistatic, anti-pilling, normal temperature and pressure and Mao Communists dye.用陽離子改性纖維織成的織物，在用陽離子染料進行染色時，With cationic modified fiber woven into the fabric, when dyeing with a cationic dye,具有色調鮮明、深染性好、吸盡率高、耐日光堅勞度和煙褪色牢度好等優點。Has a distinct tone, deep dyeing, good exhaustion rate, the degree of resistance to sunlight and smoke fade Caine labor fastness and good.在拼色染色時，染料相容性好。When mixed colors dyed, dye compatibility.在高溫染浴中，穩定性好，對包括普通聚酯纖維在內的其他纖維的玷污性小，In the high-temperature dye bath, good stability, to other fibers, including polyester fiber, including the general taint of small,向纖維內部的擴散速率快，無環境污染現象，染浴中pH值變化大，染料穩定性高。Inside the fiber diffusion rate, no environmental contamination, the pH of the dye bath big change, high dye stability.目前我國有山東華源化工有限公司以及揚州有機化工廠等廠家生產。Currently, there are Shandong Huayuan Chemical Co., Ltd. and Yangzhou organic chemical plants and other manufacturers.
