Preparation
The Nilit Plant
(One) Geographical Orientation (Geographical novelty)
The Nilit plant was established in Migdal Haemek in the early 1970s.
1.
Find Migdal Haemek on the map.
2.
Why, in your opinion, was the plant established in Migdal
Haemek?
(Two) General Familiarization with the Subject (cognitive novelty)
1.
Read the article “Nylon” by Pesach Borovsky and Amos
Shatner, in “Knowledge”, 19:6, p.15
2.
Mark the key sentences important terms and concepts with
which you are unfamiliar. (Each with a different marking).
3.
Divide the article into sub-subjects and in a few sentences write
down the information that appears in the article on each sub-subject.
(a)
(b)
(c)
(d)
4.
Check the meaning of the new terms with your teacher.
(Three)
Familiarization with the Process (cognitive novelty)
Experiment on nylon production.
1.
What are the starting materials in the experiment? Write down their formulae.
2.
Describe the reaction that takes lace.
3.
Is the process exothermic or endothermic? Explain using thermodynamic
terms.
4.
Which additional product is obtained?
5.
What problems may arise in an industrial production process resulting from
these starting materials?
6.
Suggest ways of solving these problems.
7.
Suggest alternative staring materials for the industrial production of nylon.
8.
Describe the reaction that will take place between them.
1
9.
How can the process conversion percentage be increased?
10.
What factors are likely to reduce the efficiency percentage?
11.
How can the efficiency of the process be increased?
12.
Examine the nylon thread obtained. Can it be used in its
present form? Explain.
13.
What, in your opinion, are the actions that should be taken with
the polymer in order to turn it into nylon thread that is strong and
tear-resistant?
14.
What, in your opinion, are the problems likely to arise when the
process is converted from a laboratory process into an industrial
process (transposition)? In your answer, relate to the chemical
and technological aspects.
15.
Compile a list of the various uses of nylon (using the article you
have read). Try to determine the properties that must be given
to the polymer so it is suitable for any use.
