EDTA常溫常壓下為白色粉末，能溶于氫氧化鈉、碳酸鈉及氨溶液中，能溶于沸水，微溶于冷水，不溶于醇及一般有機(jī)溶劑。為了更好的使用它，下面跟著氫氧化鉀廠家來(lái)充分了解EDTA的特性及產(chǎn)品用途吧。

EDTA is a white powder under normal temperature and pressure. It can be dissolved in sodium hydroxide, sodium carbonate and ammonia solutions, soluble in boiling water, slightly soluble in cold water, and insoluble in alcohol and general organic solvents. In order to better use it, let's follow the potassium hydroxide manufacturer to fully understand the characteristics and product uses of EDTA.

EDTA的特性

Characteristics of EDTA

EDTA是一種重要的絡(luò)合劑。EDTA用途很廣，可用作彩色感光材料沖洗加工的漂白定影液，染色助劑，纖維處理助劑，化妝品添加劑，血液抗凝劑，洗滌劑，穩(wěn)定劑，合成橡膠聚合引發(fā)劑。

EDTA is an important complexing agent. EDTA has a wide range of uses. It can be used as bleaching fixative, dyeing agent, fiber processing agent, cosmetic additive, blood anticoagulant, detergent, stabilizer, synthetic rubber polymerization initiator for the washing and processing of color sensitive materials.

EDTA是螯合劑的代表性物質(zhì)，能和堿金屬、稀土元素和過(guò)渡金屬等形成穩(wěn)定的水溶性絡(luò)合物。除鈉鹽外，還有銨鹽及鐵、鎂、鈣、銅、錳、鋅、鈷、鋁等各種鹽，這些鹽各有不同的用途。

EDTA is a representative substance of chelating agent, which can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salt, there are also ammonium salt and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt and aluminum, which have different uses.

EDTA是一種優(yōu)良的鈣、鎂離子螯合劑，用作乳液聚合所用水的螯合劑，除去Ca2+、Mg2+、Fe2+、Fe3+等金屬離子。也用作厭氧膠的絡(luò)合劑，即用EDTA處理甲基丙烯酸雙酯，除去過(guò)渡金屬離子，能促進(jìn)過(guò)氧化物分解的影響，對(duì)提高厭氧膠穩(wěn)定性的效果非常好。

EDTA is an excellent chelating agent for calcium and magnesium ions. It is used as a chelating agent for water used in lotion polymerization to remove metal ions such as ca2+, mg2+, fe2+, fe3+. It is also used as a complexing agent for anaerobic glue, that is, EDTA is used to treat the double ester of methacrylate, remove the transition metal ions, and eliminate the influence that can promote the decomposition of peroxides, which has a very good effect on improving the stability of anaerobic glue.

水處理方面的應(yīng)用：

Application in water treatment:

EDTA具有廣泛的配位能力，能與幾乎所有的金屬離子形成穩(wěn)定的螯合物，而且其金屬螯合物在微酸性條件下具有良好的溶解性，所以很早就在紡織行業(yè)中用做有害金屬離子的抑制劑和水的軟化劑。由于其金屬離子螯合物的水溶性很好，在用水設(shè)備的清洗方面的研究和應(yīng)用越來(lái)越多。

EDTA has a wide range of coordination ability, can form stable chelates with almost all metal ions, and its metal chelates have good solubility under slightly acidic conditions, so it has long been used as an inhibitor of harmful metal ions and a softener of water in the textile industry. Due to the good water solubility of its metal ion chelates, more and more researches and applications have been made in the cleaning of water equipment.

在農(nóng)業(yè)上的應(yīng)用：

Application in agriculture:

EDTA系列螯合劑的Cu、Ca、Fe、Mg、Zn等金屬鹽具有溶解性能好、易吸收等優(yōu)點(diǎn)，成為微肥的良好來(lái)源，并且這些螯合態(tài)的金屬鹽相互混合后不影響其溶解性能，有利于作為多元復(fù)合微肥使用。而且EDTA有參與反應(yīng)的羧基，可以生成鉀鹽、氨鹽等，在補(bǔ)充微量元素的同時(shí)，補(bǔ)充鉀肥和氮肥。對(duì)成本和效果進(jìn)行綜合考慮，它在很長(zhǎng)一段時(shí)間內(nèi)將會(huì)是螯合態(tài)微肥的，所以在我國(guó)的應(yīng)用量也越來(lái)越大，應(yīng)用范圍也越來(lái)越廣。

The Cu, CA, Fe, Mg, Zn and other metal salts of EDTA series chelating agents have the advantages of good solubility and easy absorption, and become a good source of micronutrient fertilizers. Moreover, these chelated metal salts do not affect their solubility after mixing with each other, which is conducive to the use as multi-element composite micronutrient fertilizers. In addition, EDTA has carboxyl groups participating in the reaction, which can generate potassium salts and ammonia salts, and supplement potassium fertilizer and nitrogen fertilizer while supplementing trace elements. Considering the cost and effect comprehensively, it will be the first choice of chelated micronutrient fertilizer for a long time, so it will be applied more and more widely in China.

EDTA系列螯合劑在照相、紡織、印染、造紙、日化、化學(xué)分析等方面也有廣泛應(yīng)用。另外要注意儲(chǔ)存于陰涼、通風(fēng)的庫(kù)房，密封保存。運(yùn)輸途中應(yīng)防曝曬、雨淋，防高溫。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.yiqijieneng.cn咨詢了解吧。

EDTA series chelating agents are also widely used in photography, textile, printing and dyeing, papermaking, daily chemicals and chemical analysis. In addition, it should be stored in a cool and ventilated warehouse and sealed. During transportation, it shall be protected from sun exposure, rain and high temperature.
