| Introduction | aluminum isopropoxide, also known as isopropyl aluminum oxide, English name is aluminum isopropoxide, abbreviated as AIP. When it is first produced, it is a colorless viscous liquid, which condenses into a solid state in 5-10 days. Aluminum isopropoxide on the market is mostly white translucent block, cylindrical small solid or powder, soluble in isopropanol, ethanol, toluene, benzene, carbon tetrachloride, chloroform and other organic solvents (heated to 70 ° C or more easily dissolved), water decomposition, strong water absorption, easy to decompose into aluminum hydroxide and isopropanol. |
| preparation method | is obtained by reacting metallic aluminum with isopropanol under the catalysis of mercuric chloride. In a 1L flask equipped with a reflux condenser and a calcium chloride drying tube were placed 1mol of aluminium wire or aluminium flakes, and 300ml of anhydrous isopropanol was obtained by distillation using industrial isopropanol with the addition of 5% of sodium by mass. And 0.5g of hgcl2. Heating to reflux was continued, and when boiling started, 2ml of carbon tetrachloride was added via the condenser, and the heating was continued to guide the sudden start of hydrogen evolution. Heat sources were removed and sometimes required cooling. When the violent reaction is calm, continue to boil until the aluminum is completely reacted (about 6~12h), after the solvent is distilled out, the residue is distilled under reduced pressure, the product was collected at a boiling point of 130-140 °c/933Pa(7mmHg). The yield was 90% ~ 95%. The product is usually cured after 1 to 2 days, and can be stored in a glass bottle sealed with paraffin. |
| aluminum isopropoxide hydrolysis | aluminum isopropoxide hydrolysis is one of the methods to produce pseudo boehmite, aluminum isopropoxide is hydrolyzed to obtain pseudoboehmite and isopropyl alcohol (isopropyl alcohol can be recovered), and pseudoboehmite can obtain high purity pseudoboehmite by one-time distillation. High purity and high purity alumina can be obtained by calcination of high purity pseudo boehmite. This process route is a formal process route for the preparation of alumina by alcoholysis. |
| Use | used as a reducing agent, a strong dehydrating agent used as a raw material for a dehydrating agent, a catalyst, and a water repellent. can be used as a positive grade material for lithium batteries. as a reducing agent and a strong dehydrating agent, it is an intermediate of hormone drugs such as isophytoalcohol, testosterone, progesterone, and norgestrel, and is also one of the raw materials of aluminate coupling agent, which is used as a raw material of a dehydrating agent, a catalyst, and a water repellent. Can be used for lithium battery positive materials. reducing agent, strong dehydrating agent. Organic Synthesis. Paint, paint composition. Fabric sizing. |
| production method | is obtained by the reaction of isopropanol and aluminum under the catalysis of alumina. Raw material consumption quota: isopropyl alcohol 1255kg/t, aluminum 166kg/t. |
