- Again china ranks first as country in export(double the US)
- Japan mostly imports natural resources fossil fuels, lumber
- Japan imports goods like electronics, machinery and optical instruments
=> Japan’s comparative advantage
b. Quotas
Japan imposes a quota rate on 17 products to Korea, mainly Agricultural
Products and fish
Ex) Quota of 2.4million sheets of Korean Seawe

이번 실험에서는 니트로벤젠을 염산과 철에 의해 환원시켜 아닐린을 합성한다.
아닐린을 합성하고 이를 정제하기 위해서 온도조절, steam distillation, simple distillation, liquid drying을 단계적으로 실시한다.
아닐린
Aniline(C6H7N)
Boiling Point : 184 ºC
Melting Point : -6 ºC
Atomic weight : 93.0 g/mol
Density : 1.0215 g
4) Methods to measure density
Specific gravity-bottle method
Sink-and-float method
Density gradient method
Displacement method
Sink-and-float method
uses heavy, light solvents and a solution that has the same density of our target polymer.
ρ₁ = the density of heavy solvent
ѵ₁ = the volume ratio of heavy solvent
ρ₂ = the density of light solvent
ѵ₂ = the v
