hello dear viewers and

00:00:09

subscribers of my channel in this video we will

00:00:10

look at the production and for a mil of acetate

00:00:15

acetic foam lava ether

00:00:17

imagine yourself as a colorless liquid with a

00:00:19

fruity smell the smell of pears pear senza in

00:00:23

other words mix with

00:00:26

ethyl alcohol diethyl ether hara

00:00:29

forms are difficult to dissolve in water and has a

00:00:33

boiling point of

00:00:34

one hundred forty-two degrees to obtain we

00:00:38

will need 15 milliliters of glacial

00:00:41

acetic acid 29 milliliters because of

00:00:44

it you will feast then and

00:00:46

one milliliter of concentrated sulfuric

00:00:48

acid from a concentration of 96 percent into a

00:00:51

round-bottomed flask located in a

00:00:54

sand bath, pour acetic acid in turn

00:01:05

and freeze the new spirit

00:01:19

and 1 liter of

00:01:25

concentrated sulfuric acid,

00:01:35

we will equip this whole thing with a reflux condenser and

00:01:38

we will boil it to

00:01:42

obtain vinegar and esters. We

00:01:45

assembled such a setup consisting of a

00:01:48

flask and a reflux condenser.

00:01:52

We will boil this mixture for about 15 minutes.

00:01:55

In theory, we need to boil it with a water trap,

00:01:59

but I don’t have one there it turns out the

00:02:03

end of the reaction is determined by how much

00:02:07

water is

00:02:09

formed in this trap and this in

00:02:12

turn is calculated by the equation here

00:02:17

the reaction mass has boiled now for 15

00:02:21

minutes it boils and turn it off received

00:02:27

and took the quote add 50 milliliters of

00:02:30

cold water

00:02:45

shake the whole thing

00:03:01

Eric transfer it to a separating funnel

00:03:05

we salt the bottom layer of water and a

00:03:16

5 percent solution of sodium carbonate is taken into the same separating funnel,

00:03:20

we will see the release of bubbles of

00:03:25

carbon dioxide and the whole thing is also with a

00:03:36

bolg to get rid of the

00:03:40

remaining acid from time to time

00:03:44

releasing the pressure, in the end we

00:03:46

get 29 where liters of vinegar for

00:03:49

sweet

00:03:50

ether for further use, this

00:03:54

ether needs to be dried with anhydrous

00:03:57

calcium chloride and distilled with an am reflux condenser,

00:04:01

collecting the boiling fraction within the range from 138

00:04:05

to 142 degrees. Whoever liked it, like it,

Description:

В данном ролике рассмотрим получение грушевой эссенции,она же изоамилацетат.Изоамилацетат применяется как растворитель нитроцеллюлозы, входит в состав какого то клея для киноплёнок(сейчас не применяется,в связи с новыми технологиями). В пищевой промышленности популярен под названием грушевой эссенции. Оказывает вредное действие на центральную нервную систему,поэтому не стоит его нюхать. ЭТО ОЧЕНЬ ОПАСНО!
