Methyl ethyl ketone peroxide (MEKP) is an organic peroxide, a high explosive similar to acetone peroxide. Please do not post entire problem sets or questions that you haven't attempted to answer yourself. Unsaturated polyester resin was used as matrix, methyl ethyl ketone peroxide (MEKP) was used as a catalyst, and cobalt naphthenate was used as an accelerator.
(surfing) The chemical methyl ethyl ketone peroxide which is used as a catalyst to harden the fibreglass resin in surfboard manufacture and repair. Strictly speaking the abbreviation would be MEKP, but the shorthand MEK is frequently found. In this case, we again have one carbon on one side of the C=O, but now the other side has three carbons, which is called a propyl group. Therefore there is one carbon on one side of the C=O (the methyl group) and there are two carbons on the other side (the ethyl group). It is a four carbon chain with an oxygen double bonded to the second carbon.
Their respective properties are presented in a table below:. Which means "The top lager of the condensate....? Strictly speaking the abbreviation would be MEKP, but the shorthand MEK is frequently found. Join Yahoo Answers and get 100 points today.
Press J to jump to the feed. We send our large stuff out to get repainted lol, MEK/MPK it's usually only used to soften up sealant, but you gotta be quick to wipe it off of any paint you might get it on or itll just liquify it, as I'm sure you already know. The reaction of polyester will occur at the thickest cross section sending out a wave of heat, which cures resin to a solid glass-like hardness. Inhalation: Take precautions to prevent a fire (e.g. MEK is a Food and Drug Administration (FDA)-approved indirect food additive for adhesives and polymers. The methyl ethyl ketone (MEK) peroxide which is easily made is an explosive when concentrated. ? Catalyst Chart for polyester resin, gel coat and vinyl ester marine resins. Roselle plants were collected from Selangor, Malaysia. The retted stem of the roselle plants was washed in running water and the fibers were removed manually. These were procured from Vasavibala Resins (P) Ltd, Chennai, Tamil Nadu-India. This quality is convenient for distillation of moisture in certain applications. Which of the following correctly lists the five atoms in order of increasing size (smallest to largest)? Methyl ethyl ketone peroxide (MEKP) is an organic peroxide used in the marine industry. Methyl ethyl ketone is a nice smelling liquid often used as an organic industrial solvent.
Call a Poison Centre or doctor if the victim feels unwell.
Why? MEKP is a colorless, oily liquid whereas acetone peroxide is a white powder at STP ; MEKP is slightly less sensitive to shock and temperature, and more stable in storage. Catalyst Chart Volume of Catalyst to Be Used with Polyester Resins Methyl Ethyl Ketone Peroxide-Percent by Weight 1% 1.25% 1.5% 1.75% Resin(1) Volume Drop cc oz Drop cc oz Drop cc oz Drop cc oz 4 ounce 32 1-1/4 1/32 40 1-1/2 3/64 48 1-3/4 1/16 56 2 1/16+ This is apparently a thing now that people are writing exams from home. But it can be used safely in dilute solutions, like benzoyl peroxide that many use to treat acne.
MEK is methyl ethyl ketone. I assume MPK would be methyl propyl ketone. About methyl ethyl ketone peroxide (MEKP) MEKP is a catalyst used in the composites industry for polyester and vinyl ester resins. MEKP is an oily colorless liquid, with a faint acetone-like smell (some sources say mint), slightly soluble in water, but miscible with various organic solvents. MEKP is methyl ethyl ketone peroxide, which is the catalyst for polyester resin. Methyl ethyl ketone peroxide (MEKP) was used as a hardener. In that case, there is a five carbon chain with an oxygen double bonded to the second carbon. removes tool for defrauded students, CDC to shorten quarantine for those exposed to virus. The methyl ethyl ketone (MEK) peroxide which is easily made is an explosive when concentrated. In biology class today my teacher played a porn video to show what they were talking about Should I talk to the principal to get her fired. MEKP Ratio Chart Polyester Resin Polyester resin cures by an exothermic (heat) reaction created by promoters (cobalt & amine) and activator Methyl Ethel Ketone Peroxide (MEKP). I'm an aircraft mechanic and I use both of these solvents interchangeably, on almost a daily basis. MEKP Ratio Chart Polyester Resin Polyester resin cures by an exothermic (heat) reaction created by promoters (cobalt & amine) and activator Methyl Ethel Ketone Peroxide (MEKP).
Synonyms for MEK are 2-butanone, ethyl methyl ketone, and methyl acetone. Initialism. MEK will not work as a catalyst for resin. Press question mark to learn the rest of the keyboard shortcuts. remove sources of ignition).Move victim to fresh air.
These compounds have been out there a long time in the chemistry books, problem is that the internet has opened them to many folks who should not make or use them but sometimes do.. Unlike Acetone, MEK forms an azeotrope with water, which means that methyl ethyl ketone and water mix together to form a constant boiling point that cannot be affected by distillation. ( Initialism ) ( head ) (organic compound) methyl ethyl ketone.
(If I’m remembering anything I’ve learned correctly at all). watchbands, belts).Flush … Is this 'Charlie Brown' scene racially problematic? It is a four carbon chain with an oxygen double bonded to the second carbon. MEK is a natural component of many foods, including apple juice, beans, chicken, honey and a variety of cheeses. These two are quite different. Cookies help us deliver our Services. MEK is methyl ethyl ketone. The reaction of polyester will occur at the thickest cross section sending out a wave of heat, which cures resin to a solid glass-like hardness. It reacts with the resin to turn it from a liquid to a solid (cure it). Skin Contact: Take off contaminated clothing, shoes and leather goods (e.g. I assume MPK would be methyl propyl ketone. Explosive Methyl ethyl ketone peroxide is a primary explosive, sensitive to shock and friction, though less so than TATP , with a detonation velocity of 5200 m/s. The properties of sisal, banana, and naturally woven coconut sheath fiber (untreated) are shown in Table 3.1. MEKP is an organic peroxide. New comments cannot be posted and votes cannot be cast.
They both smell pretty similar, and I assume, based on the SDS, they're both just as toxic and gnarly. I never paid attention in chemistry but I know that the difference may be as simple as one atom bonding way over yonder instead of right here :p. MEK is methyl ethyl ketone. Follow up question: since MEK is smaller would it be a tad stronger in some since there would be more of a dipole?
Fox paid 7-figure settlement over bogus conspiracy story, Crucial new data on the efficacy of cloth masks, 'Voice' singer's tough night in Knockout Rounds, Snubbed former Nike exec auctioning rare Jordan shoes, David Maas, NBA halftime showman, dies of COVID-19, Education Dept. MEK is both less soluble and less volatile than acetone. Therefore there is one carbon on one side of the C=O (the methyl group) and there are two carbons on the other side (the ethyl group). It can be made when you mix MEK and hydrogen peroxide under the right conditions. The fibers were then cleaned and dried in sunlight for 4 days. Also please don't use this sub to cheat on your exams!! Methyl ethyl ketone is a nice smelling liquid often used as an organic industrial solvent. Still have questions? Get your answers by asking now. History hasn't been kind to fighters on comeback trail, Obama crushed by Colbert in 'waste basket-ball', Chappelle's Netflix show removed at his request. Given hypothetical elements Q, R, S and T that are found on the same period. It can be made when you mix MEK and hydrogen peroxide under the right conditions.
