詳細(xì)信息(中文):
具體用途
絡(luò)合劑、掩蔽劑、沉淀劑、還原劑。分析中用以檢定和測(cè)定鈹、鈣、鉻、金、錳、鍶、釷等金屬離子。顯微微晶分析檢驗(yàn)鈉和其他元素。沉淀鈣、鎂、釷和稀土元素。校準(zhǔn)高錳酸鉀和硫酸鈰溶液的標(biāo)準(zhǔn)溶液。漂白劑。助染劑。也可用來(lái)除去衣服上的鐵銹建筑行業(yè)在涂刷外墻涂料前、由于墻面堿性較強(qiáng)應(yīng)先涂刷草酸除堿。
印染工業(yè)用作顯色助染劑、漂白劑、醫(yī)藥中間體。塑料工業(yè)用于生產(chǎn)聚氯乙烯、氨基塑料、脲醛塑料。

用作酚醛樹(shù)脂合成的催化劑,催化反應(yīng)溫和,過(guò)程比較平穩(wěn),持續(xù)時(shí)間最長(zhǎng)。草酸丙酮溶液能催化環(huán)氧樹(shù)脂固化反應(yīng),縮短固化時(shí)間。也用作合成脲醛樹(shù)脂、三聚氰胺甲醛樹(shù)脂的pH值調(diào)節(jié)劑。還可加入聚乙烯醇縮甲醛水溶性膠黏劑中提高干燥速度和粘接強(qiáng)度。亦用作脲醛樹(shù)脂的固化劑、金屬離子螯合劑??捎米鱇MnO4氧化劑制備淀粉膠黏劑的促進(jìn)劑,加快氧化速度,縮短反應(yīng)時(shí)間。

作漂白劑
草酸主要用作還原劑和漂白劑,用于生產(chǎn)抗菌素和冰片等藥物以及提煉稀有金屬的溶劑、染料還原劑、鞣革劑等。

草酸還可用于鈷-鉬-鋁催化劑的生產(chǎn)、金屬和大理石的清洗及紡織品的漂白。

用于金屬表面清洗和處理,稀土元素提取、紡織印染、皮革加工、催化劑制備等。

作還原劑
在有機(jī)合成工業(yè)主要用于生產(chǎn)對(duì)苯二酚、季戊四醇、草酸鈷、草酸鎳、沒(méi)食子酸等化工產(chǎn)品。

塑料工業(yè)用于生產(chǎn)聚氯乙烯、氨基塑料、脲醛塑料、漆片等。

染料工業(yè)用于制造鹽基品綠等。

印染工業(yè)可代替乙酸,用作色素染料的顯色助染劑、漂白劑。

此外,草酸還可用于合成各種草酸酯、草酸鹽和草酰胺等產(chǎn)品,而以草酸二乙酯及草酸鈉、草酸鈣等產(chǎn)量最大

The specific purpose

Complexing agent, masking agent, precipitator, reducing agent. It is used to determine beryllium, calcium, chromium, gold, manganese, strontium, thorium and other metal ions. Sodium and other elements were examined by microcrystalline analysis. Precipitated calcium, magnesium, thorium and rare earth elements. Standard solution for calibration of potassium permanganate and cerium sulfate. Bleach. To dye. Can also be used to remove the rust on the clothing building industry before painting exterior wall paint, because the wall is more alkaline should be painted first oxalic acid to remove alkali.

Printing and dyeing industry as color AIDS, bleach, pharmaceutical intermediates. The plastics industry is used to produce PVC, amino plastics, urea-formaldehyde plastics.


As a catalyst for phenolic resin synthesis, the catalytic reaction is mild, the process is relatively stable, the longest duration. Oxalate acetone solution can catalyze curing reaction of epoxy resin and shorten curing time. Also used as a pH regulator for the synthesis of urea formaldehyde resin and melamine formaldehyde resin. It can also be added into polyvinyl formal water-soluble adhesive to improve drying speed and bonding strength. Also used as curing agent and metal ion chelating agent of uf resin. It can be used as a promoter for preparing starch adhesive with KMnO4 oxidant.


As a bleach

Oxalic acid is mainly used as reducing agent and bleaching agent for the production of drugs such as antimicrobials and borneol as well as solvents for the extraction of rare metals, dyes reducing agent, tanning agent, etc.


Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, the cleaning of metals and marble and the bleaching of textiles.


Used for surface cleaning and treatment of metals, extraction of rare earth elements, textile printing and dyeing, leather processing, catalyst preparation, etc.


As a reducing agent

In the organic synthesis ind
