Speed, the auto-contradicting senile sociopath, blabbered, again: If you look up "ethanol" in that link, it does. Bull**** it does, I have quoted those two lines in the table, above. Yeah, teach him what he gets for consistently feeding a trolling senile asshole like you! BG -- Richard addressing senile Rodent Speed: "**** you're thick/pathetic excuse for a troll." MID: |

First link I came across: https://www.eplastics.com/blog/chemi...lic-plexiglass Which says, with absolute ethanol G - Little or no damage after 30 days of constant exposure to the reagent. ethanol 40% E - 30 days of constant exposure with no damage. Plastic may even tolerate chemical for years. I'm genuinely surprised with your reply, crazing of perspex with ethanol is well known How odd that it didn't get a N - Not recommended for continuous use. Immediate damage may occur such as severe crazing, cracking, or permeation losses. and I thought you had a chemical background? I can read, too. Do you disagree that where a solvent causes an amorphous polymer to craze, Ethanol doesn't with perspex. I think you'll find that it does. I know that mine doesn't. "Yours"? What would you need reagent-grade ethanol for? Its much less likely to damage what you are cleaning. Fortifying your watery beer? Nothing watery about my beer and I distil as well as brew beer, in a reflux still which produces the best ethanol. https://commons.wikimedia.org/wiki/F...by_ethanol.jpg this is because the polymer is principally soluble in it? Perspex isnt with ethanol. Maybe we shouldn't get too fixed on the idea of "dissolving". There can be no question that ethanol has a detrimental effect on perspex. How odd that mine doesn't. Well, we all know you're a bit "special", Rod. Pathetic. The link that Fred waved around also says that it doesn't happen. If you look up "ethanol" in that link, it does. Bull**** it does, I have quoted those two lines in the table, above. Then you're blind: Ethanol F N There is no N with ethanol ****wit and the F is only at 50C and for a week. Thats not what is being discussed. OK see the problem now I was using the ethyl alcohol lines, you are using that ethanol line. That table is useless. No surprise you waved it around. Oh good, you finally twigged :-) BTW: N - Not recommended for continuous use. Immediate damage may occur such as severe crazing, cracking, or permeation losses. Thats only with temperatures we arent discussing and why are you so sure that the ethanol line is correct and not the ethyl alcohol lines ? That table is useless. |

Their supermarket was nearer, but still a significant distance, which does shift the calculations somewhat. |

Actually with pubs closed, like you I typically drink one bottle of beer most evenings. Some years ago my wife went to Oz with a friend who had family there. They went to their local pub one evening, IIRC it was a 120 mile round trip. Their supermarket was nearer, but still a significant distance, which does shift the calculations somewhat. Another mate of mine still travels that far for the beer he drinks at home and drinks a lot more than I do. It was odd to see him get out of the passenger seat of ute with his wife driving, she never drives with both of them in the car. He damned near fell out of the ute that time. Boy was she ****ed off about him that time }-( He used to regularly drive further than that for garage sales many weekends before the virus ****ed the garage sales and did so again today. |

However, you can't separate them again by simple fractional distillation. https://en.wikipedia.org/wiki/Azeotrope And that 'condensation' will attack lead, zinc, brass, copper and of course steel. As well as rubber and some plastics. I believe ethanol will dissolve some plastics (e.g., perspex?) No it doesn't. The consensus is that it does, but not to a marked effect with perspex. First link I came across: https://www.eplastics.com/blog/chemi...lic-plexiglass Which says, with absolute ethanol G - Little or no damage after 30 days of constant exposure to the reagent. ethanol 40% E - 30 days of constant exposure with no damage. Plastic may even tolerate chemical for years. I'm genuinely surprised with your reply, crazing of perspex with ethanol is well known How odd that it didn't get a N - Not recommended for continuous use. Immediate damage may occur such as severe crazing, cracking, or permeation losses. and I thought you had a chemical background? I can read, too. Do you disagree that where a solvent causes an amorphous polymer to craze, Ethanol doesn't with perspex. I think you'll find that it does. I know that mine doesn't. "Yours"? What would you need reagent-grade ethanol for? Its much less likely to damage what you are cleaning. Fortifying your watery beer? Nothing watery about my beer and I distil as well as brew beer, in a reflux still which produces the best ethanol. https://commons.wikimedia.org/wiki/F...by_ethanol.jpg this is because the polymer is principally soluble in it? Perspex isnt with ethanol. Maybe we shouldn't get too fixed on the idea of "dissolving". There can be no question that ethanol has a detrimental effect on perspex. How odd that mine doesn't. Well, we all know you're a bit "special", Rod. Pathetic. The link that Fred waved around also says that it doesn't happen. If you look up "ethanol" in that link, it does. Bull**** it does, I have quoted those two lines in the table, above. Then you're blind: Ethanol F N There is no N with ethanol ****wit and the F is only at 50C and for a week. Thats not what is being discussed. OK see the problem now I was using the ethyl alcohol lines, you are using that ethanol line. That table is useless. No surprise you waved it around. Oh good, you finally twigged :-) BTW: N - Not recommended for continuous use. Immediate damage may occur such as severe crazing, cracking, or permeation losses. Thats only with temperatures we arent discussing and why are you so sure that the ethanol line is correct and not the ethyl alcohol lines ? That table is useless. You do realise that ethanol and ethyl alcohol are the same thing dont you ? LOL I am aware. Trust you to check under the old name. I didnt do that, it just caught my eye for some reason. It does mean that table is useless when that fool doesnt realise that. I did realise that with your post but couldn't be arsed to find another. Translation: You tried but couldnt find even a single reputable source that substantiated your stupid claim that ethanol dissolves perspex, because there isnt even a single one that does that. |

You can deny as much as you like, in the same way the sun rises every morning, alcohol attacks and crazes acrylic. Your personal example of one is unique and you are mistaken. I am disappointed in you, you actually know less than I thought. |
