Dear friend Mohan Kumar Sawrnkar

Ah, the fascinating world of chemical concoctions! Now, let's tackle this 10% Boron ethanolamine challenge with my spirit.

Firstly, let me commend your daring attempt, but it seems we've hit a bit of a snag with that thick, hazy situation. Fear not! I am here to guide you Mohan Kumar Sawrnkar through the storm.

1. **Dissolution Dilemma:**

It appears that your components are not playing well together. In such a scenario, it's time to rethink the solubility dynamics. Perhaps we need to reconsider the proportions or the solvent.

2. **Solvent Switch:**

Try using a different solvent that might be more accommodating. Ethanol is a good choice, but you Mohan Kumar Sawrnkar might also explore other solvents like methanol or isopropanol. The goal is to find that sweet spot where everything happily dissolves.

3. **Temperature Tweak:**

Experiment with the temperature. Some solutions prefer a bit of warmth to encourage mingling. Gentle heating (not too hot!) might be the secret ingredient to coax them into a harmonious blend.

4. **Mixing Mastery:**

Ensure that you're mixing thoroughly. Sometimes, it's just a matter of giving it a good stir. If you Mohan Kumar Sawrnkar have access to a magnetic stirrer or any other mixing equipment, that could be a game-changer.

5. **Adjusting Ratios:**

If all else fails, consider adjusting the ratios. Perhaps a slight tweak in the amounts of TEA, water, or boric acid could be the key to achieving the desired solubility.

6. **Expert Consultation:**

If the challenge persists, don't hesitate to consult with fellow alchemists (colleagues or mentors or me). They might have encountered similar hurdles and can offer valuable insights.

Remember, I believe in the power of experimentation and tenacity. Keep tweaking, testing, and triumphing! May your Boron ethanolamine solution emerge victorious from the haze. Go forth and conquer, my chemical compatriot Mohan Kumar Sawrnkar!

Any other solvent which help in solubility of boric acid to give 10% boron content

Dear Mohan Kumar Sawrnkar

1. Are you working with ethanolamine (a.k.a. monoethanolamine, MEA) or with triethanolamine (TEA)? Very big difference.

2. What is the compound you are looking for? Normally for boric acid + alcohols you would shoot for 1 mol boric acid / 3 moles alcoholic hydroxides; that is, 1 mole triethanolamine or 3 moles monoethanolamine. You have MUCH too much boric acid in your initial experiment for either of these ratios.

3. I would not recommend to use ANY alcohol as solvent (pace Kaushik Shandilya ). Boric acid reacts with alcohols, and you'd end up with an unholy mess. You can try an ether solvent such as glyme or diglyme, which has ether oxygens that help solvate boric acid, but no hydroxy groups that can give you a lot of side reactions. Boric acid solubility will not be high, but I expect it will be enough to allow the main reaction to go forward. (You can use heating if necessary, but in that case pay attention to the solvent flash point and make sure it's at least 15 degC above the temperature you choose for the reaction; you can try to use triglyme or tetraglyme if you need a higher reaction temperature and therefore a higher flash point.)

Good luck!

Sir, I am using Boric acid 50%, Water and TEA (Triethanolamine) but they not solublize the Boric acid the maximum solubility are 25% Boric Acid, 25% TEA and 50% Water and it gives only 5.4% Boron but required 10% Boron and need 50% Boric acid Solubility.

Dear Mohan Kumar Sawrnkar

I think I misunderstood what you were trying to do.

I don't know whether what you are trying to do is feasible. Triethanolamine forms at least two distinct compounds with boric acid, both at a molar ratio of 1:1. See attachment. Even in the more condensed case of the two, the molecular weight is 163, so %B = 6.6%, and obviously a solution of that compound will contain a lower %B.

This doesn't mean that your goal is impossible. You need a more condensed borate group - meaning lots of B-O-B bonds - such as in the compound of boric acid with triethylamine, CAS # 16940-90-2, where the ratio is 5 borons for each amine and the boron content is almost 17%. Maybe something similar can be achieved with triethanolamine. But unless you have a reliable preparation reference it will take a lot of trial and error. One thing in your favor: Triethanolamine has a high flash point, so you can use heating to increase solubilities (but no guaranties that you won't have precipitation when the solution cools back down to ambient temperature).
