生产间苯二甲酸二乙酯Between the production of diethyl phthalate
由间苯二甲酸制备的间苯二甲酸二乙酯（DEIP）主要用于甲苯二异氰酸生产中做特种溶剂，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，易于分离，可加速光气反应，减少副反应，产品纯度高等特点。Has good solubility, easy separation, can accelerate phosgene, reduce side effects, and high product purity.
由间苯二甲酸二苯酯和3，3’-二氨基联苯胺（DAB）进行熔融缩聚反应制得的聚苯并咪唑是杂环高分子中第一个被考虑用作耐高温结构胶粘剂的产品，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,其特点是瞬时耐高温性能优良，广泛用作铝合金、不锈钢等金属材料、金属蜂窝结构、聚酰亚胺薄膜以及硅片等材料的胶粘剂。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.
生产阳离子可染树脂改性单体Production of cationic dyeable resin-modified monomeric
由间苯二甲酸制得的间苯二甲酸二甲酯-5-磺酸钠（SIPM）是聚酯切片的改性单体，Prepared from isophthalic acid, dimethyl isophthalate 5-sodium (SIPM) is a modified monomer of polyester chips,可使改性后的聚酯纤维染色更鲜艳浓厚，着色性好，同时具有抗起球效果。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可生产阳离子改性涤纶长丝Introduction SIPM produce cationic modified polyester filament polyester slices，其外观虽然与普通涤纶长丝没有太大的区别，Although its appearance and ordinary polyester filament is not much difference,但是由于采用了阳离子改性，不仅大大改善了纤维的吸色性能，However, due to the use of cationically modified, not only greatly improve the color absorption properties of the fibers,而且降低了结晶度，从而使染色分子易于渗透，使得纤维容易染色。But also reduces the degree of crystallinity, so that the dye molecule is easy to penetrate the fibers easily dyed.这种纤维既保证了阳离子易染，同时又可增加纤维的微孔，This fiber is easy both to ensure the cationic dye, but also increase the fiber pores,提高了纤维的上染率、透气性、吸湿性，从而进一步适应聚酯纤维的仿真丝化。Improve the fiber dyeing rate, permeability, moisture absorption, thereby further adapt silk of polyester fibers.通过仿真丝化可使织物柔软透气、舒适、抗静电、常温常压可染。Make by silk fabric of soft, breathable, comfortable, antistatic, temperature and pressure can be dyed.通过阳离子改性多功能仿毛，可使织物具有手感柔软、抗静电、抗起毛起球、常温常压与毛共染。By cation-modified multifunctional wool, make fabric has a soft, antistatic, anti-pilling, normal temperature and pressure and Mao Communists dye.用阳离子改性纤维织成的织物，在用阳离子染料进行染色时，With cationic modified fiber woven into the fabric, when dyeing with a cationic dye,具有色调鲜明、深染性好、吸尽率高、耐日光坚劳度和烟褪色牢度好等优点。Has a distinct tone, deep dyeing, good exhaustion rate, the degree of resistance to sunlight and smoke fade Caine labor fastness and good.在拼色染色时，染料相容性好。When mixed colors dyed, dye compatibility.在高温染浴中，稳定性好，对包括普通聚酯纤维在内的其他纤维的玷污性小，In the high-temperature dye bath, good stability, to other fibers, including polyester fiber, including the general taint of small,向纤维内部的扩散速率快，无环境污染现象，染浴中pH值变化大，染料稳定性高。Inside the fiber diffusion rate, no environmental contamination, the pH of the dye bath big change, high dye stability.目前我国有山东华源化工有限公司以及扬州有机化工厂等厂家生产。Currently, there are Shandong Huayuan Chemical Co., Ltd. and Yangzhou organic chemical plants and other manufacturers.
